Enum GpuEncodedPaint 

pub enum GpuEncodedPaint {
    Image(GpuEncodedImage),
    LinearGradient(GpuLinearGradient),
    RadialGradient(GpuRadialGradient),
    SweepGradient(GpuSweepGradient),
    BlurredRoundedRect(GpuBlurredRoundedRect),
}

One encoded paint of any kind.

Records are compared by their bytes (GpuEncodedPaint::as_bytes) rather than field-wise: the bytes are the contract the shader reads.

Variants

Image(GpuEncodedImage)

An image.

LinearGradient(GpuLinearGradient)

A linear gradient.

RadialGradient(GpuRadialGradient)

A radial gradient.

SweepGradient(GpuSweepGradient)

A sweep gradient.

BlurredRoundedRect(GpuBlurredRoundedRect)

A blurred rounded rectangle.

Implementations

impl GpuEncodedPaint

pub const fn paint_type(&self) -> PaintType

The paint type a strip instance names this record by.

pub fn as_bytes(&self) -> &[u8]

This paint’s bytes, exactly as they land in the encoded-paint texture.

pub fn byte_len(&self) -> usize

This paint’s size in bytes — always a multiple of the 16-byte texel.

pub fn texel_len(&self) -> u32

The number of texels this paint occupies.

pub fn serialized_len(paints: &[Self]) -> usize

The total byte length of paints serialized back to back.

pub fn serialize_to_buffer( paints: &[Self], buffer: &mut [u8], ) -> Result<usize, EngineError>

Serializes paints back to back into the front of buffer, returning the number of bytes written.

buffer is the full padded upload buffer, so anything past the returned length keeps whatever it already held — a paint index only ever addresses a record that was written.

Errors

Returns EngineError::AtlasError when buffer is shorter than the serialized paints, rather than writing a partial record.

pub fn texel_offsets(paints: &[Self]) -> Vec<u32>

The texel each paint in paints starts at, in serialization order — the index the shader looks a paint up by.
