Function lz4_flex::block::compress_into

pub fn compress_into(
    input: &[u8], 
    output: &mut [u8]
) -> Result<usize, CompressError>

Compress all bytes of input into output. The method chooses an appropriate hashtable to lookup duplicates and calls compress_into_with_table. output should be preallocated with a size of get_maximum_output_size.

Returns the number of bytes written (compressed) into output.
