pub struct TrieTestHarness { /* private fields */ }trie and (crate features test-utils) only.Expand description
General-purpose test harness for storage trie tests.
Manages a base storage dataset, computes expected roots via StorageRoot, and generates
V2 proofs via StorageProofCalculator using mock cursors.
Implementations§
Source§impl TrieTestHarness
impl TrieTestHarness
Sourcepub fn new(storage: BTreeMap<FixedBytes<32>, Uint<256, 4>>) -> TrieTestHarness
pub fn new(storage: BTreeMap<FixedBytes<32>, Uint<256, 4>>) -> TrieTestHarness
Creates a new test harness from a map of hashed storage slots to values.
Sourcepub fn get_root_with_updates(
&self,
changeset: &BTreeMap<FixedBytes<32>, Uint<256, 4>>,
) -> (FixedBytes<32>, StorageTrieUpdates)
pub fn get_root_with_updates( &self, changeset: &BTreeMap<FixedBytes<32>, Uint<256, 4>>, ) -> (FixedBytes<32>, StorageTrieUpdates)
Computes the storage root and trie updates after applying the given changeset on top of the current base storage.
Builds a HashedPostStateCursorFactory overlay, derives a prefix set from the
changeset keys, and passes both into StorageRoot::new_hashed.
Sourcepub fn apply_changeset(
&mut self,
changeset: BTreeMap<FixedBytes<32>, Uint<256, 4>>,
)
pub fn apply_changeset( &mut self, changeset: BTreeMap<FixedBytes<32>, Uint<256, 4>>, )
Merges changeset into the base storage (zero values remove entries) and
rebuilds the harness from scratch with the resulting storage.
Sourcepub const fn hashed_address(&self) -> FixedBytes<32>
pub const fn hashed_address(&self) -> FixedBytes<32>
Returns the hashed address used for all storage trie operations.
Sourcepub const fn storage(&self) -> &BTreeMap<FixedBytes<32>, Uint<256, 4>>
pub const fn storage(&self) -> &BTreeMap<FixedBytes<32>, Uint<256, 4>>
Returns a reference to the base storage dataset.
Sourcepub const fn original_root(&self) -> FixedBytes<32>
pub const fn original_root(&self) -> FixedBytes<32>
Returns the expected storage root.
Sourcepub const fn storage_trie_updates(&self) -> &StorageTrieUpdates
pub const fn storage_trie_updates(&self) -> &StorageTrieUpdates
Returns a reference to the storage trie updates.
Sourcepub fn set_trie_nodes(
&mut self,
trie_nodes: BTreeMap<Nibbles, BranchNodeCompact>,
)
pub fn set_trie_nodes( &mut self, trie_nodes: BTreeMap<Nibbles, BranchNodeCompact>, )
Replaces the trie cursor factory with one backed by the given trie nodes.
Sourcepub fn trie_cursor_factory(&self) -> MockTrieCursorFactory
pub fn trie_cursor_factory(&self) -> MockTrieCursorFactory
Returns a clone of the mock trie cursor factory.
Sourcepub fn hashed_cursor_factory(&self) -> MockHashedCursorFactory
pub fn hashed_cursor_factory(&self) -> MockHashedCursorFactory
Returns a clone of the mock hashed cursor factory.
Sourcepub fn root_node(&self) -> ProofTrieNodeV2
pub fn root_node(&self) -> ProofTrieNodeV2
Obtains the root node of the storage trie via StorageProofCalculator.
Sourcepub fn proof_v2(
&self,
targets: &mut [ProofV2Target],
) -> (Vec<ProofTrieNodeV2>, Option<FixedBytes<32>>)
pub fn proof_v2( &self, targets: &mut [ProofV2Target], ) -> (Vec<ProofTrieNodeV2>, Option<FixedBytes<32>>)
Generates storage proofs for the given targets using StorageProofCalculator.
Also computes and returns the root hash (if the proof contains a root node) by reusing the calculator after the proof call.
Sourcepub fn minimize_trie_updates(&self, updates: &mut StorageTrieUpdates)
pub fn minimize_trie_updates(&self, updates: &mut StorageTrieUpdates)
Removes all entries from updates that are redundant with the starting storage
trie updates.
A storage node is redundant if it exists in the starting set with the same value.
A removed node is redundant if it was already absent from the starting set.
The is_deleted flag is cleared if it matches the starting value.

§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>
renamed to 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
