brotli-rs1

A brotli compressor and decompressor.

Usage

brotli-rs [FLAGS]

Overview

A brotli compressor and decompressor that with an interface avoiding the rust stdlib. This makes it suitable for embedded devices and kernels. It is designed with a pluggable allocator so that the standard lib's allocator may be employed. All included code is safe.

Flags

-catable, --catable: Enable concatable mode, so that the generated data can be added to block generated with --apendable

-nothreadpool, --nothreadpool: Disables the work thread pool

-appendable, --appendable: Enables apendable mode, so that the datastream can be extended with more data from the --catable mode

-magic, --magic: Enables magic number as the first bytes, so that a brotli compressed stream can be easily detected

-customdictionary=[FILE]: Reads a custom dictionare from file

--dump-dictionary: Prints the dictionary used

-utf8: Forces the utf8 context mode in the compression

-msb: Forces the msb context mode in the compression

-lsb: Forces the lsb context mode in the compression

-signed: Forces the signed context mode in the compression

-efficient: favor cpu efficiency over low latency

-lowlatency: favor cpu low latency over efficiency

-i: display the intermediate representation of metablocks

Examples

compresses the content of /tmp/input and writes it to /tmp/output: $ brotli-rs -c /tmp/input /tmp/output
