Expand description
Performs LZ4_HC block compression.
Ensure that the destination slice has enough capacity.
If dst.len()
is smaller than lz4::max_compressed_size(src.len())
,
this function may fail.
Returns the number of bytes written into the destination buffer.
Example
use lzzzz::{lz4, lz4_hc};
let data = b"The quick brown fox jumps over the lazy dog.";
let mut buf = [0u8; 256];
// The slice should have enough capacity.
assert!(buf.len() >= lz4::max_compressed_size(data.len()));
let len = lz4_hc::compress(data, &mut buf, lz4_hc::CLEVEL_DEFAULT)?;
let compressed = &buf[..len];
