Function get_bytes_in_archive_from_hash 

pub fn get_bytes_in_archive_from_hash(
    archive_path: &str,
    hash: &str,
) -> Result<(Vec<u8>, Header), SigmfError>

Finds the .sigmf-meta member of the tar file at archive_path whose SHA-512 digest equals hash, returning its contents and tar header.

hash is compared exactly against the lowercase hexadecimal digest produced by hash_from_slice.

Errors

Returns SigmfError::ResourceLimit if a metadata member examined before a match exceeds the 1,000,000-byte metadata size limit, SigmfError::NotFound if no member matches, or SigmfError::Io if the archive cannot be opened or read.
