Enum JsonDigest 

pub enum JsonDigest {
    Sha3([u8; 32]),
    Blake3([u8; 32]),
}

A typed, parsed representation of a JSON digest string like "cjubdcpA0Ff..." or "cmursDCff...".

Each variant carries its own hash size — currently both 32 bytes, but future hashers with different output sizes can add variants without changing the public API.

Round-trips through [Display] / [FromStr] and supports serde and SCALE codec.

Variants

Sha3([u8; 32])

SHA3-256 Merkle-tree hash (prefix cj).

Blake3([u8; 32])

BLAKE3-256 Merkle-tree hash (prefix cm).

Implementations

impl JsonDigest

pub fn kind_char(self) -> char

The single-letter code used in the digest string after the leading c.

pub fn is_sha3(self) -> bool

Returns true if this is a SHA3-256 json-digest.

pub fn is_blake3(self) -> bool

Returns true if this is a BLAKE3-256 json-digest.

pub fn as_bytes(&self) -> &[u8]

Return the raw hash bytes as a slice, regardless of variant.
