Crate tiny_webp 

Encodes RGB and RGBA pixel buffers as lossy WebP files.

Version 0.1.0 writes one VP8 key frame in a RIFF WebP container. It uses DC prediction, the Y2 transform path, one token partition, and a fixed quantizer chosen from Options::quality. The encoder keeps exact alpha from non-opaque RGBA input in an uncompressed ALPH chunk.

The library is no_std and allocates through alloc. It reads and writes byte slices in memory. Callers own file and stream I/O.

Options is #[non_exhaustive], so build one from its default and assign the fields that change.

let mut opts = tiny_webp::Options::default();
opts.quality = 90;
opts.alpha = tiny_webp::Alpha::Discard;

let rgba = [128u8; 16];
let webp = tiny_webp::encode_rgba(&rgba, 2, 2, &opts)?;
assert_eq!(&webp[..4], b"RIFF");
