Enum HashAlgorithm 

pub enum HashAlgorithm {
    Sha256,
}

Hash algorithm used by an IntegrityHash pin on #import. Only Sha256 is wired in v3++ b-2; the enum exists so future agents can add Sha512 / Blake3 (or SRI multi-algo) without an AST shape change.

Variants

Sha256

Implementations

impl HashAlgorithm

pub fn as_str(&self) -> &'static str

Canonical lowercase identifier as it appears in source (sha256:"..."). Lookups in the parser / analyzer compare against this so the casing is fixed in one place.

pub fn from_ident(name: &str) -> Option<Self>

Reverse of HashAlgorithm::as_str. Returns None for unknown names so the caller can emit a position-aware parse / analyzer diagnostic.

pub fn hex_len(&self) -> usize

Expected hex-digest length (one byte = two hex chars) for the algorithm. Used by the analyzer to reject obvious typos before it tries to verify the import.

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.
