Package testtype contains types for testing deephash.

ExcludeFields returns an option that modifies the hashing for T to include all struct fields of T except those provided in fields.

Hash returns the hash of v.

HasherForType returns a hash that is specialized for the provided type.

IncludeFields returns an option that modifies the hashing for T to only include the named struct fields.

Update sets last to the hash of v and reports whether its value changed.

Hasher is a value passed to [SelfHasher.Hash] that allow implementations to hash themselves in a structured manner.

Sum is an opaque checksum type that is comparable.

Option is an optional argument to HasherForType.

SelfHasher is implemented by types that can compute their own hash by writing values through the provided [Hasher] parameter.
