Struct PackedRgba16fLayout 

pub struct PackedRgba16fLayout {
    pub surface_w: usize,
    pub surface_h: usize,
    pub bytes_per_texel: usize,
    pub pitch: usize,
}

Geometry of the RGBA16F-packed surface backing a planar F16 image tensor.

ANGLE only supports one float (type, internal_format) pair for IOSurface import: (GL_HALF_FLOAT, GL_RGBA) = RGBA16F (8 bytes/texel). To map a [C, H, W] f16 planar tensor onto such a surface, 4 contiguous f16 elements are packed into each RGBA16F texel, yielding a surface of (W/4, C*H) texels at 8 bytes/texel. The byte stream is identical to a (nonexistent) R16F (W, C*H) surface and can be consumed as &[f16] with shape [1, C, H, W] without rearrangement.

Obtain via packed_rgba16f_layout — never construct directly.

Fields

surface_w: usize

Surface width in texels (width / 4).

surface_h: usize

Surface height in texels (planes * height).

bytes_per_texel: usize

Bytes per RGBA16F texel (always 8).

pitch: usize

Row pitch in bytes (surface_w * 8).

Trait Implementations

impl Clone for PackedRgba16fLayout

fn clone(&self) -> PackedRgba16fLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PackedRgba16fLayout

impl Debug for PackedRgba16fLayout

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

impl Eq for PackedRgba16fLayout

impl PartialEq for PackedRgba16fLayout

fn eq(&self, other: &PackedRgba16fLayout) -> 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.
