Re-exported predicates

The following predicates are exported from this file while their implementation is defined in imported modules or non-module files loaded by this module.

Source open_hash_stream(+OrgStream, -HashStream, +Options) is det
Open a filter stream on OrgStream that maintains a hash. The hash can be retrieved at any time using stream_hash/2. Provided options:
One of md5, sha1, sha224, sha256, sha384 or sha512. Default is sha1.
If true (default), closing the filter stream also closes the original (parent) stream.
Source stream_hash(+HashStream, -Digest:atom) is det
Unify Digest with a hash for the bytes send to or read from HashStream. Note that the hash is computed on the stream buffers. If the stream is an output stream, it is first flushed and the Digest represents the hash at the current location. If the stream is an input stream the Digest represents the hash of the processed input including the already buffered data.
