Module encoder 

Pure Rust WebP encoder helpers.

Current scope is still-image WebP encode. The lossless path targets VP8L with transforms, adaptive Huffman coding, simple backward references, and an optional color cache. The lossy path targets opaque still images and emits a minimal intra-only VP8 bitstream.

Structs

LosslessEncodingOptions

Lossless encoder tuning knobs.

LossyEncodingOptions

Lossy encoder tuning knobs.

Enums

EncoderError

Error type used by encoding entry points.
