Struct ContextPrecompiles
pub struct ContextPrecompiles<DB>where
DB: Database,{ /* private fields */ }Expand description
Precompiles context.
Implementations§
§impl<DB> ContextPrecompiles<DB>where
DB: Database,
impl<DB> ContextPrecompiles<DB>where
DB: Database,
pub fn new(spec_id: PrecompileSpecId) -> ContextPrecompiles<DB>
pub fn new(spec_id: PrecompileSpecId) -> ContextPrecompiles<DB>
Creates a new precompiles context at the given spec ID.
This is a cheap operation that does not allocate by reusing the global precompiles.
pub fn from_static_precompiles(
precompiles: &'static Precompiles,
) -> ContextPrecompiles<DB>
pub fn from_static_precompiles( precompiles: &'static Precompiles, ) -> ContextPrecompiles<DB>
Creates a new precompiles context from the given static precompiles.
NOTE: The internal precompiles must not be StatefulMut or call will panic.
This is done because the default precompiles are not stateful.
pub fn from_precompiles(
precompiles: HashMap<Address, ContextPrecompile<DB>, RandomState>,
) -> ContextPrecompiles<DB>
pub fn from_precompiles( precompiles: HashMap<Address, ContextPrecompile<DB>, RandomState>, ) -> ContextPrecompiles<DB>
Creates a new precompiles context from the given precompiles.
pub fn addresses_set(&self) -> HashSet<Address, RandomState>
pub fn addresses_set(&self) -> HashSet<Address, RandomState>
Returns precompiles addresses as a HashSet.
pub fn addresses<'a>(
&'a self,
) -> Box<dyn ExactSizeIterator<Item = &'a Address> + 'a>
pub fn addresses<'a>( &'a self, ) -> Box<dyn ExactSizeIterator<Item = &'a Address> + 'a>
Returns precompiles addresses.
pub fn contains(&self, address: &Address) -> bool
pub fn contains(&self, address: &Address) -> bool
Returns true if the precompiles contains the given address.
pub fn call(
&mut self,
address: &Address,
bytes: &Bytes,
gas_limit: u64,
evmctx: &mut InnerEvmContext<DB>,
) -> Option<Result<PrecompileOutput, PrecompileErrors>>
pub fn call( &mut self, address: &Address, bytes: &Bytes, gas_limit: u64, evmctx: &mut InnerEvmContext<DB>, ) -> Option<Result<PrecompileOutput, PrecompileErrors>>
Call precompile and executes it. Returns the result of the precompile execution.
Returns None if the precompile does not exist.
pub fn to_mut(
&mut self,
) -> &mut HashMap<Address, ContextPrecompile<DB>, RandomState>
pub fn to_mut( &mut self, ) -> &mut HashMap<Address, ContextPrecompile<DB>, RandomState>
Returns a mutable reference to the precompiles map.
Clones the precompiles map if it is shared.

§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);Set foreground color to white using white().
use yansi::Paint;
painted.white();§fn bright_black(&self) -> Painted<&T>

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

§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling [Attribute] value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi [Quirk] value.
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():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the [Condition] value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);§impl<T> Pipe for Twhere
