[−][src]Function lzzzz::lz4f::compress
pub fn compress(
src: &[u8],
dst: &mut [u8],
prefs: &Preferences
) -> Result<usize>
Performs LZ4F compression.
Ensure that the destination slice have enough capacity.
If dst.len()
is smaller than lz4f::max_compressed_size(src.len())
,
this function may fail.
Returns the number of bytes written into the destination buffer.
Example
Compress data with the default compression mode:
use lzzzz::lz4f; let prefs = lz4f::Preferences::default(); let data = b"The quick brown fox jumps over the lazy dog."; let mut buf = [0u8; 2048]; // The slice should have enough capacity. assert!(buf.len() >= lz4f::max_compressed_size(data.len(), &prefs)); let len = lz4f::compress(data, &mut buf, &prefs)?; let compressed = &buf[..len];
