Struct TextTextureKey 

pub struct TextTextureKey {
    content: String,
    family: Option<String>,
    size_bits: u32,
    color_bits: [u32; 4],
    line_height_bits: u32,
    letter_spacing_bits: u32,
    weight: u16,
    italic: bool,
    align: u8,
    wrap_width_bits: Option<u32>,
    width_px: u32,
    height_px: u32,
}

Cache key for a rendered text texture.

Hashes the content + style + wrap width + output dimensions; f32 fields go through to_bits() so equality is exact-bit (avoids the NaN-aware quirks of std::cmp::Eq on floats). Same canonical NaN bits hash identically — fine because callers re-pass the same style value across frames.

Implementations

impl TextTextureKey

pub fn new(text: &WispText, width_px: u32, height_px: u32) -> Self

Build a key from a WispText and the requested texture dimensions.

Trait Implementations

impl Clone for TextTextureKey

fn clone(&self) -> TextTextureKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextTextureKey

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

Formats the value using the given formatter.

impl Hash for TextTextureKey

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 TextTextureKey

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