Struct AtlasGeometry 

#[non_exhaustive]
pub struct AtlasGeometry {
    pub cell_w: u32,
    pub cell_h: u32,
    pub layers: u32,
}

The packing of glyph cells into an array texture: a fixed ATLAS_COLSxATLAS_ROWS grid of cell_wxcell_h glyph cells per layer, across layers layers.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

cell_w: u32

Glyph cell width in texels (one unscaled font pixel per texel).

cell_h: u32

Glyph cell height in texels.

layers: u32

Number of array layers.

Implementations

impl AtlasGeometry

pub const fn new(cell_w: u32, cell_h: u32, capacity: u32) -> Self

Geometry with enough layers to hold capacity glyph slots (at least one layer).

pub const fn tex_w(&self) -> u32

One layer’s texture width in texels.

pub const fn tex_h(&self) -> u32

One layer’s texture height in texels.

pub const fn locate(slot: u32) -> (u32, u32, u32)

Maps a flat slot index to its (layer, glyph_column, glyph_row).

Trait Implementations

impl Clone for AtlasGeometry

fn clone(&self) -> AtlasGeometry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AtlasGeometry

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

Formats the value using the given formatter.

impl PartialEq for AtlasGeometry

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