Struct FeatureHash 

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

A 128-bit feature hash.

Feature hashes are candidate-index keys, not stable identifiers: they are valid only within one FEATURE_SCHEMA_VERSION. Each is a BLAKE3 digest over a domain string, the schema version and the feature’s length-prefixed inputs, truncated to 16 bytes.

Implementations

impl FeatureHash

pub const fn from_bytes(bytes: [u8; 16]) -> Self

Wrap hash bytes produced earlier by this module.

pub const fn as_bytes(&self) -> &[u8; 16]

The hash’s raw bytes.

pub fn to_hex(&self) -> String

Lowercase hex form used in reports.

impl Eq for FeatureHash

impl Hash for FeatureHash

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

Feeds this value into the given Hasher.

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

impl PartialEq for FeatureHash

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for FeatureHash

fn partial_cmp(&self, other: &FeatureHash) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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