type Err = HexToArrayError

The associated error which can be returned from parsing.

impl Hash for TapLeafHash

const LEN: usize = 32usize

fn as_byte_array(&self) -> &Self::Bytes

Returns a reference to the underlying byte array.

fn all_zeros() -> Self

Returns an all zero hash.

fn hash(data: &[u8]) -> Self

fn hash_byte_chunks<B, I>(byte_slices: I) -> Self

where B: AsRef<[u8]>, I: IntoIterator<Item = B>,

fn eq(&self, other: &TapLeafHash) -> bool

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

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