Struct RunCacheKey 

pub struct RunCacheKey<'a> {
    pub text: &'a str,
    pub script: Script,
    pub direction: RunDirection,
    pub style_id: u64,
}

Deterministic, hashable cache key for shaped glyph output.

Two runs producing equal RunCacheKey values can share the same shaped glyph buffer, enabling efficient caching of shaping results.

Fields

text: &'a str

The text content of the run.

script: Script

The resolved script.

direction: RunDirection

The text direction.

style_id: u64

Style discriminant (e.g., hash of font weight + style + size).

Trait Implementations

impl<'a> Clone for RunCacheKey<'a>

fn clone(&self) -> RunCacheKey<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for RunCacheKey<'a>

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

Formats the value using the given formatter.

impl Hash for RunCacheKey<'_>

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<'a> PartialEq for RunCacheKey<'a>

fn eq(&self, other: &RunCacheKey<'a>) -> 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.
