Assets a string snapshot.

This is the most simplistic of all assertion methods. It just accepts a string to store as snapshot an does not apply any other transformations on it. This is useful to build ones own primitives.

assert_snapshot_matches!("snapshot_name", "reference value to snapshot");

Optionally a third argument can be given as expression which will be stringified as debug expression. For more information on this look at the source of this macro and other assertion macros.
