Function zstd_sys::ZSTD_compress

pub unsafe extern "C" fn ZSTD_compress(
    dst: *mut c_void,
    dstCapacity: usize,
    src: *const c_void,
    srcSize: usize,
    compressionLevel: c_int
) -> usize

Simple API Compresses src content as a single zstd compressed frame into already allocated dst. Hint : compression runs faster if dstCapacity >= ZSTD_compressBound(srcSize). @return : compressed size written into dst (<= `dstCapacity), or an error code if it fails (which can be tested using ZSTD_isError()).
