Supertype for stateful digest handles.

Subtype of Sink. Putting a str or bin value updates the digest state with its bytes.

Methods

update data

Updates the digest state with the bytes of data.

Parameters:

Name	Type	Description

let sink = Blake3()
sink.put "ab"
sink.put b"c"
assert_eq $sink.digest() (blake3 "abc")

digest

Returns the current digest bytes without consuming the handle.

Returns: bin - Digest snapshot

let second = state.digest()
assert_eq $first $second
state.update "def"
assert_eq $state.digest().hex()
