Function zstd_safe::decompress

pub fn decompress(dst: &mut [u8], src: &[u8]) -> Result<usize, usize>

ZSTD_decompress

compressedSize : must be the exact size of some number of compressed and/or skippable frames.

dstCapacity is an upper bound of originalSize.

If user cannot imply a maximum upper bound, it's better to use streaming mode to decompress data.

Returns the number of bytes decompressed into dst (<= dstCapacity), or an errorCode if it fails (which can be tested using ZSTD_isError()).
