pub struct InvalidBlockSelection(/* private fields */);
Expand description
Describes the invalid block hooks that should be installed.
§Example
Create a InvalidBlockSelection
from a selection.
use reth_node_core::args::{InvalidBlockHookType, InvalidBlockSelection};
let config: InvalidBlockSelection = vec![InvalidBlockHookType::Witness].into();
Implementations§
Source§impl InvalidBlockSelection
impl InvalidBlockSelection
Sourcepub fn try_from_selection<I, T>(
selection: I,
) -> Result<InvalidBlockSelection, <T as TryInto<InvalidBlockHookType>>::Error>
pub fn try_from_selection<I, T>( selection: I, ) -> Result<InvalidBlockSelection, <T as TryInto<InvalidBlockHookType>>::Error>
Creates a new unique InvalidBlockSelection
from the given items.
§Note
This will dedupe the selection and remove duplicates while preserving the order.
§Example
Create a selection from the InvalidBlockHookType
string identifiers
use reth_node_core::args::{InvalidBlockHookType, InvalidBlockSelection};
let selection = vec!["witness", "prestate", "opcode"];
let config = InvalidBlockSelection::try_from_selection(selection).unwrap();
assert_eq!(
config,
InvalidBlockSelection::from([
InvalidBlockHookType::Witness,
InvalidBlockHookType::PreState,
InvalidBlockHookType::Opcode
])
);
Create a unique selection from the InvalidBlockHookType
string identifiers
use reth_node_core::args::{InvalidBlockHookType, InvalidBlockSelection};
let selection = vec!["witness", "prestate", "opcode", "witness", "prestate"];
let config = InvalidBlockSelection::try_from_selection(selection).unwrap();
assert_eq!(
config,
InvalidBlockSelection::from([
InvalidBlockHookType::Witness,
InvalidBlockHookType::PreState,
InvalidBlockHookType::Opcode
])
);
Sourcepub fn to_selection(&self) -> HashSet<InvalidBlockHookType>
pub fn to_selection(&self) -> HashSet<InvalidBlockHookType>
Clones the set of configured InvalidBlockHookType

Methods from Deref<Target = HashSet<InvalidBlockHookType>>§
1.0.0 · Sourcepub fn capacity(&self) -> usize
Available on crate feature map
only.
pub fn capacity(&self) -> usize
map
only.Returns the number of elements the set can hold without reallocating.
§Examples
use std::collections::HashSet;
let set: HashSet<i32> = HashSet::with_capacity(100);
assert!(set.capacity() >= 100);
1.0.0 · Sourcepub fn iter(&self) -> Iter<'_, T> ⓘ
Available on crate feature map
only.
pub fn iter(&self) -> Iter<'_, T> ⓘ
map
only.An iterator visiting all elements in arbitrary order.
The iterator element type is &'a T
.
§Examples
use std::collections::HashSet;
let mut set = HashSet::new();
set.insert("a");
set.insert("b");
// Will print in an arbitrary order.
for x in set.iter() {
println!("{x}");
}
§Performance
In the current implementation, iterating over set takes O(capacity) time instead of O(len) because it internally visits empty buckets too.
1.0.0 · Sourcepub fn len(&self) -> usize
Available on crate feature map
only.
pub fn len(&self) -> usize
map
only.Returns the number of elements in the set.
§Examples

v.insert(1);
assert_eq!(v.len(), 1);
1.0.0 · Sourcepub fn is_empty(&self) -> bool
Available on crate feature map
only.
pub fn is_empty(&self) -> bool
map
only.Returns true
if the set contains no elements.
§Examples
use std::collections::HashSet;
let mut v = HashSet::new();
assert!(v.is_empty());
v.insert(1);
assert!(!v.is_empty());
1.9.0 · Sourcepub fn hasher(&self) -> &S
Available on crate feature map
only.
pub fn hasher(&self) -> &S
map
only.Returns a reference to the set’s BuildHasher
.
§Examples

let hasher: &RandomState = set.hasher();
1.0.0 · Sourcepub fn difference<'a>(
&'a self,
other: &'a HashSet<T, S>,
) -> Difference<'a, T, S> ⓘ
Available on crate feature map
only.
pub fn difference<'a>( &'a self, other: &'a HashSet<T, S>, ) -> Difference<'a, T, S> ⓘ
map
only.Visits the values representing the difference,
i.e., the values that are in self
but not in other
.
§Examples
use std::collections::HashSet;
let a = HashSet::from([1, 2, 3]);
let b = HashSet::from([4, 2, 3, 4]);
// Can be seen as `a - b`.
for x in a.difference(&b) {
println!("{x}"); // Print 1
}
let diff: HashSet<_> = a.difference(&b).collect();
assert_eq!(diff, [1].iter().collect());
// Note that difference is not symmetric,
// and `b - a` means something else:
let diff: HashSet<_> = b.difference(&a).collect();
assert_eq!(diff, [4].iter().collect());
1.0.0 · Sourcepub fn symmetric_difference<'a>(
&'a self,
other: &'a HashSet<T, S>,
) -> SymmetricDifference<'a, T, S> ⓘ
Available on crate feature map
only.
pub fn symmetric_difference<'a>( &'a self, other: &'a HashSet<T, S>, ) -> SymmetricDifference<'a, T, S> ⓘ
map
only.Visits the values representing the symmetric difference,

or in other
but not in both.
§Examples
use std::collections::HashSet;
let a = HashSet::from([1, 2, 3]);
let b = HashSet::from([4, 2, 3, 4]);
// Print 1, 4 in arbitrary order.
for x in a.symmetric_difference(&b) {
println!("{x}");
}
let diff1: HashSet<_> = a.symmetric_difference(&b).collect();
let diff2: HashSet<_> = b.symmetric_difference(&a).collect();
assert_eq!(diff1, diff2);
assert_eq!(diff1, [1, 4].iter().collect());
1.0.0 · Sourcepub fn intersection<'a>(
&'a self,
other: &'a HashSet<T, S>,
) -> Intersection<'a, T, S> ⓘ
Available on crate feature map
only.
pub fn intersection<'a>( &'a self, other: &'a HashSet<T, S>, ) -> Intersection<'a, T, S> ⓘ
map
only.Visits the values representing the intersection,
i.e., the values that are both in self
and other
.
When an equal element is present in self
and other
then the resulting Intersection
may yield references to
one or the other. This can be relevant if T
contains fields which
are not compared by its Eq
implementation, and may hold different
value between the two equal copies of T
in the two sets.
§Examples
use std::collections::HashSet;
let a = HashSet::from([1, 2, 3]);
let b = HashSet::from([4, 2, 3, 4]);
// Print 2, 3 in arbitrary order.
for x in a.intersection(&b) {

map
only.Visits the values representing the union,
i.e., all the values in self
or other
, without duplicates.
§Examples
use std::collections::HashSet;
let a = HashSet::from([1, 2, 3]);
let b = HashSet::from([4, 2, 3, 4]);
// Print 1, 2, 3, 4 in arbitrary order.
for x in a.union(&b) {
println!("{x}");
}
let union: HashSet<_> = a.union(&b).collect();
assert_eq!(union, [1, 2, 3, 4].iter().collect());
1.0.0 · Sourcepub fn contains<Q>(&self, value: &Q) -> bool
Available on crate feature map
only.
pub fn contains<Q>(&self, value: &Q) -> bool
map
only.Returns true
if the set contains a value.
The value may be any borrowed form of the set’s value type, but
Hash
and Eq
on the borrowed form must match those for
the value type.
§Examples
use std::collections::HashSet;
let set = HashSet::from([1, 2, 3]);
assert_eq!(set.contains(&1), true);
assert_eq!(set.contains(&4), false);
1.9.0 · Sourcepub fn get<Q>(&self, value: &Q) -> Option<&T>
Available on crate feature map
only.
pub fn get<Q>(&self, value: &Q) -> Option<&T>
map
only.Returns a reference to the value in the set, if any, that is equal to the given value.

on the borrowed form must match those for
the value type.
§Examples
use std::collections::HashSet;
let set = HashSet::from([1, 2, 3]);
assert_eq!(set.get(&2), Some(&2));

1.0.0 · Sourcepub fn is_disjoint(&self, other: &HashSet<T, S>) -> bool
Available on crate feature map
only.
pub fn is_disjoint(&self, other: &HashSet<T, S>) -> bool
map
only.Returns true
if self
has no elements in common with other
.
This is equivalent to checking for an empty intersection.
§Examples
use std::collections::HashSet;
let a = HashSet::from([1, 2, 3]);
let mut b = HashSet::new();
assert_eq!(a.is_disjoint(&b), true);
b.insert(4);
assert_eq!(a.is_disjoint(&b), true);
b.insert(1);
assert_eq!(a.is_disjoint(&b), false);
1.0.0 · Sourcepub fn is_subset(&self, other: &HashSet<T, S>) -> bool
Available on crate feature map
only.

§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self
with the foreground set to
value
.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red()
and
green()
, which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg()
:
use yansi::{Paint, Color};
painted.fg(Color::White);

builder methods like on_red()
and

, which have the same functionality but
are pithier.
§Example
Set background color to red using fg()

attribute-specific builder methods like bold()
and
underline()
, which have the same functionality
but are pithier.
§Example

This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask()
and
wrap()
, which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk()

Enable wrapping using wrap()

applies. Replaces any previous condition.

§Example
