Struct CanonicalIdentity 

pub struct CanonicalIdentity { /* private fields */ }

A role-separated canonical semantic identity.

Equality includes the role, schema, algorithm, and digest.

Implementations

impl CanonicalIdentity

pub fn for_font_container_bytes(data: &[u8]) -> Self

Derives the Font Container identity of exact container bytes.

pub const fn role(self) -> CanonicalIdentityRole

The semantic role separated by this identity.

pub const fn schema(self) -> &'static str

The identity schema used by this release.

pub const fn algorithm(self) -> &'static str

The deterministic digest algorithm used by the schema.

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

The deterministic 128-bit digest in big-endian order.

Trait Implementations

impl Clone for CanonicalIdentity

fn clone(&self) -> CanonicalIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CanonicalIdentity

impl Debug for CanonicalIdentity

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

Formats the value using the given formatter.

impl Display for CanonicalIdentity

Renders the role-qualified digest, the form used by diagnostics and inspect.

This is a readable projection, not the equality contract: comparisons must use the whole CanonicalIdentity, which also separates schema and algorithm.

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

Formats the value using the given formatter.

impl Eq for CanonicalIdentity

impl Hash for CanonicalIdentity

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 Ord for CanonicalIdentity

fn cmp(&self, other: &CanonicalIdentity) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CanonicalIdentity

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for CanonicalIdentity

fn partial_cmp(&self, other: &CanonicalIdentity) -> 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

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