Supporting shared dictionary feature

[horo-t]

Hi. I'm Tsuyoshi Horo working on Compression Dictionary Transport feature in Chromium.

SharedDictionary feature which supports Shared Brotli Compressed Data Format was merged in the C and Java implementation under google/brotli on Aug 4, 2021.

Is there any plans to support the SharedDictionary feature in the rust implementation?

Thank you.

Is the current dict support insufficient? Did Brotli change that feature?

if argument.starts_with("-dict=") && !double_dash {
  let mut dict_file = File::open(&Path::new(&argument[6..])).unwrap();
  dict_file.read_to_end(&mut dictionary).unwrap();
  continue;
}
