Struct ShapeKey 

pub struct ShapeKey {
    pub font_id: u32,
    pub font_size_px: u16,
    pub text_hash: u32,
    pub wrap_width_bucket: u16,
}

Key for caching shaped text results.

Uses version numbers and bucketed dimensions to create stable cache keys while allowing reasonable reuse across similar layouts.

Fields

font_id: u32

Font ID from the font system

font_size_px: u16

Font size in pixels (rounded to nearest integer)

text_hash: u32

Text content version (from TextValue)

wrap_width_bucket: u16

Wrap width bucketed to 4px increments (0 = no wrap)

Implementations

impl ShapeKey

pub fn new( font_id: u32, font_size: f32, text_content: &str, wrap_width: Option<f32>, ) -> Self

Create a new shape key with width bucketing.

pub fn bucketed_width(&self) -> Option<f32>

Get the actual bucketed width value.

Trait Implementations

impl Clone for ShapeKey

fn clone(&self) -> ShapeKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeKey

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

Formats the value using the given formatter.

impl Hash for ShapeKey

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 ShapeKey

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