Struct PipelineFingerprint 

pub struct PipelineFingerprint(pub [u8; 32]);

The blake3 fingerprint of a canonicalized Program. 32 bytes so collisions are cryptographically impossible for our scale.

Tuple Fields

0: [u8; 32]

Implementations

impl PipelineFingerprint

pub fn of(program: &Program) -> Self

Derive a fingerprint from a Program. Runs vyre_foundation::optimizer::passes::algebraic::canonicalize_engine::run first so semantically-equal Programs share a fingerprint.

Only program-intrinsic state is allowed into this hash. The fingerprint must stay stable across different dispatch inputs and execution-time knobs so the cache remains content-addressed rather than dispatch-addressed.

Examples

use vyre_foundation::ir::Program;
use vyre_runtime::PipelineFingerprint;

let a = Program::empty();
let b = Program::empty();

assert_eq!(PipelineFingerprint::of(&a), PipelineFingerprint::of(&b));

pub fn hex(&self) -> String

Hex-encode the fingerprint for human display + path-safe storage. Lowercase, no separators, 64 chars.

Trait Implementations

impl Clone for PipelineFingerprint

fn clone(&self) -> PipelineFingerprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PipelineFingerprint

impl Debug for PipelineFingerprint

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

Formats the value using the given formatter.

impl Eq for PipelineFingerprint

impl Hash for PipelineFingerprint

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 PipelineFingerprint

fn eq(&self, other: &PipelineFingerprint) -> 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.
