#gmlewis/flate

This is a simplified flate compression algorithm based on Go's implementation: https://cs.opensource.google/go/go/+/refs/tags/go1.23.1:src/compress/flate/deflatefast.go which has the copyright notice:

// Copyright 2016 The Go Authors. All rights reserved.

#Status

The code has been updated to support compiler:

$ moon version --all
moon 0.1.20260920 (914d7da 2026-09-20) ~/.moon/bin/moon
moonc v0.10.14+7d59c7ec9 (2026-09-18) ~/.moon/bin/moonc

Reader

source

pub(open) trait Reader {
  fn read(Self, @gmlewis/io.Slice
Slice[Byte]) -> (Int, @gmlewis/io.IOError
IOError?)
  fn read_byte(Self) -> (Byte, @gmlewis/io.IOError
IOError?)
}

The actual read interface needed by [Decompressor::new].

impl Reader for Buffer

fn read(self : @gmlewis/io.Buffer
Buffer, b : @gmlewis/io.Slice
Slice[Byte]) -> (Int, @gmlewis/io.IOError
IOError?)

source

fn read_byte(self : @gmlewis/io.Buffer
Buffer) -> (Byte, @gmlewis/io.IOError
IOError?)

Writer::close

source

fn Writer::close(self : Writer) -> @gmlewis/io.IOError

Writer::new

source

fn Writer::new(buf : &@gmlewis/io.Writer
Writer) -> Writer

Writer::new returns a new [@io.WriteCloser] compressing data at the "BestSpeed" level. It writes its (compressed) data to the provided buf.

Writer::new_dict

source

fn Writer::new_dict(w : &@gmlewis/io.Writer
Writer, dict : @gmlewis/io.Slice
Slice[Byte]) -> Writer

Writer::write

source

fn Writer::write(self : Writer, data : @gmlewis/io.Slice
Slice[Byte]) -> (Int, @gmlewis/io.IOError
IOError?)

ioeof

source

let ioeof : @gmlewis/io.IOError
IOError

writer_closed_error

source

let writer_closed_error : @gmlewis/io.IOError
IOError
