Struct ShapeCacheKey 

pub struct ShapeCacheKey {
    pub font_id: FontId,
    pub font_size_bits: FontSizeBits,
    pub text_hash: TextHash,
    pub max_width_bits: MaxWidthBits,
    pub family_hash: TextHash,
    pub line_height_bits: LineHeightBits,
}

Cache key for the Tier 2 shaping cache.

Fields

font_id: FontId

Font face identifier.

font_size_bits: FontSizeBits

Font size quantized to bits.

text_hash: TextHash

Hash of the text content.

max_width_bits: MaxWidthBits

Available width for wrapping, quantized to bits. u32::MAX represents unbounded (no wrapping).

family_hash: TextHash

Hash of the font family name.

line_height_bits: LineHeightBits

Line height quantized to bits.

Implementations

impl ShapeCacheKey

pub fn new(font_id: FontId, font_size: f32, text: &str) -> Self

pub fn with_max_width( font_id: FontId, font_size: f32, text: &str, max_width: Option<f32>, ) -> Self

Creates a new cache key with a max width for wrapping.

pub fn with_max_width_and_family( font_id: FontId, font_size: f32, text: &str, max_width: Option<f32>, family: &str, line_height: f32, ) -> Self

Creates a new cache key with max width, family, and line height.
