Function lz4::block::compress_to_buffer

pub fn compress_to_buffer(
    src: &[u8], 
    mode: Option<CompressionMode>, 
    prepend_size: bool, 
    buffer: &mut [u8]
) -> Result<usize>

Compresses the full src buffer using the specified CompressionMode, where None and Some(Default) are treated equally, writing compressed bytes to buffer.

Errors

Returns std::io::Error with ErrorKind::InvalidInput if the src buffer is too long. Returns std::io::Error with ErrorKind::Other if the compression data does not find in buffer.
