Struct Digest 

pub struct Digest(/* private fields */);

A digest of actor IDs, being built.

Implementations

impl Digest

pub fn new() -> Self

The empty set’s: all zeros.

pub fn of<'a>(ids: impl IntoIterator<Item = &'a str>) -> Self

The digest of ids.

pub fn add(&mut self, id: &str)

Fold id in. Folding the same ID in twice takes it out again.

pub fn is_zero(&self) -> bool

Whether it is all zeros: the empty set’s, or two equal sets’ folded together.

pub fn from_hex(hex: &str) -> Option<Self>

Read a digest written in hex; None when it is not 32 bytes of hex.

pub fn to_hex(&self) -> String

Its lowercase hex.
