Class Method Details

.new(bytes) ⇒ Object

Public constructor. Derives the LZ4 frame ‘Dict_ID` from the dictionary bytes (sha256 truncated to the first 4 bytes, little-endian) and forwards to the Rust extension. The id is what gets written into every emitted frame’s FrameDescriptor and what ‘#decompress` asserts the incoming frame declares before decoding.
