# brotli-rs(1)

A brotli compressor and decompressor.

## NAME

brotli-rs - A brotli compressor and decompressor.

## SYNOPSIS

**brotli-rs** \[FLAGS\]

## DESCRIPTION

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
