Struct Digest 

pub struct Digest { /* private fields */ }

A digest algorithm, bound at creation.

compute is one-shot and stateless per call (the resource is reusable), mirroring crypto.subtle.digest. The byte stream is the only ingestion path; the result is chunking-invariant. The streaming contract in README.md applies.

Security:

• A digest authenticates nothing by itself. There is deliberately no verify here: checking untrusted data against a known digest is an integrity comparison, done by the caller with a constant-time byte comparison (see README.md, “Terminology”) of compute’s result. When authenticity is needed, use a mac-key.

Implementations

impl Digest

pub async fn compute(&self, data: StreamReader<u8>) -> Result<Vec<u8>, Error>

Digest an entire byte stream. A success resolves only after the stream is fully drained (its writer dropped).

Fails only for operational reasons (error.other).

impl Digest

pub fn algorithm_name(&self) -> String

The registry name of the algorithm this resource is bound to, e.g. "SHA-256" (as crypto.subtle.digest spells it). For a digest the algorithm is the hash, so there is no separate algorithm-hash getter.

Trait Implementations

impl Debug for Digest

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

Formats the value using the given formatter.

impl From<Digest> for Digest

fn from(raw: Digest) -> Self

Converts to this type from the input type.
