Implementations§

Source§

impl SupportedCompression

Source

pub fn check(bytes: &[u8]) -> Option<Self>

If the given byte slice starts with the “magic” bytes for a supported compression family, return that family, for unsupported/uncompressed slices, return None. Based on https://en.wikipedia.org/wiki/List_of_file_signatures.
