Enum HashAlgorithm 

pub enum HashAlgorithm {
    Sha256,
    Sha512,
    Blake3,
}

The hash functions a content address (or an integrity claim over one) may name. The enum admits only strong functions — BLAKE3 (Aumasson, O’Connor, Neves & Wilcox-O’Hearn 2020) and SHA-256 / SHA-512 (NIST FIPS 180-4) — so weak functions (MD5, SHA-1) are unrepresentable: “refuse weak algorithms” is a type invariant, not a runtime branch. Praxis EMITS addresses under exactly one algorithm per format epoch (ADDRESS_ALGORITHM); it VERIFIES claims under any variant here (the W3C SRI verify-many discipline).

Trait Implementations

impl Clone for HashAlgorithm

fn clone(&self) -> HashAlgorithm

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for HashAlgorithm

impl Debug for HashAlgorithm

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

Formats the value using the given formatter.

impl Eq for HashAlgorithm

impl Hash for HashAlgorithm

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HashAlgorithm

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
