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. The buffer cannot be larger than i32::MAX. Returns std::io::Error with ErrorKind::Other if the compression data does not fit in buffer.
