pub struct MerkleTree { /* private fields */ }Expand description
A fully-balanced binary Merkle tree (i.e., a tree where the number of leaves is a power of two).
Implementations§
Source§impl MerkleTree
impl MerkleTree
Sourcepub fn new<T>(leaves: T) -> Result<MerkleTree, MerkleError>
pub fn new<T>(leaves: T) -> Result<MerkleTree, MerkleError>
Returns a Merkle tree instantiated from the provided leaves.
§Errors
Returns an error if the number of leaves is smaller than two or is not a power of two.
Sourcepub fn depth(&self) -> u8
pub fn depth(&self) -> u8
Returns the depth of this Merkle tree.
Merkle tree of depth 1 has two leaves, depth 2 has four leaves etc.
Sourcepub fn get_node(&self, index: NodeIndex) -> Result<Word, MerkleError>
pub fn get_node(&self, index: NodeIndex) -> Result<Word, MerkleError>
Returns a node at the specified depth and index value.
§Errors
Returns an error if:
- The specified depth is greater than the depth of the tree.
- The specified index is not valid for the specified depth.
Sourcepub fn get_path(&self, index: NodeIndex) -> Result<MerklePath, MerkleError>
pub fn get_path(&self, index: NodeIndex) -> Result<MerklePath, MerkleError>
Returns a Merkle path to the node at the specified depth and index value. The node itself is not included in the path.
§Errors
Returns an error if:
- The specified depth is greater than the depth of the tree.
- The specified value is not valid for the specified depth.
Sourcepub fn leaves(&self) -> impl Iterator<Item = (u64, &Word)>
pub fn leaves(&self) -> impl Iterator<Item = (u64, &Word)>
Returns an iterator over the leaves of this MerkleTree.
Sourcepub fn inner_nodes(&self) -> InnerNodeIterator<'_>
pub fn inner_nodes(&self) -> InnerNodeIterator<'_>
Returns n iterator over every inner node of this MerkleTree.
The iterator order is unspecified.
Sourcepub fn update_leaf<'a>(
&'a mut self,
index_value: u64,
value: Word,
) -> Result<(), MerkleError>
pub fn update_leaf<'a>( &'a mut self, index_value: u64, value: Word, ) -> Result<(), MerkleError>
Replaces the leaf at the specified index with the provided value.
§Errors
Returns an error if the specified index value is not a valid leaf value for this tree.

Source§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().

painted.white();Source§fn bright_black(&self) -> 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().

Source§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().

Source§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();Source§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.
Source§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);
