Struct MerkleBuoy

pub struct MerkleBuoy<D: Copy + Eq + SubAssign<u8> + Default> { /* private fields */ }

Helper struct to track depth when working with Merkle blocks.

Implementations

impl<D: Copy + Eq + SubAssign<u8> + Default> MerkleBuoy<D>

pub fn new(top: D) -> Self

pub fn level(&self) -> D

Measure the current buoy level.

pub fn push(&mut self, depth: D) -> bool

Add new item to the buoy.

Returns whether the buoy have surfaced in a result.

The buoy surfaces each time the contents it has is reduced to two depth of the same level.

Trait Implementations

impl<D: Clone + Copy + Eq + SubAssign<u8> + Default> Clone for MerkleBuoy<D>

fn clone(&self) -> MerkleBuoy<D>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<D: Debug + Copy + Eq + SubAssign<u8> + Default> Debug for MerkleBuoy<D>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<D: Default + Copy + Eq + SubAssign<u8> + Default> Default for MerkleBuoy<D>

fn default() -> MerkleBuoy<D>

Returns the “default value” for a type.

impl<D: PartialEq + Copy + Eq + SubAssign<u8> + Default> PartialEq for MerkleBuoy<D>

fn eq(&self, other: &MerkleBuoy<D>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
