More...

accepts ($value)

Tells if the provided value complies.

Parameters

mixed $value

Returns: bool

More...

problemWith ($value)

Parameters

mixed $value

Returns: string|null

More...

applyTo (Result $result)

Restricts a Result.Must do nothing with the result if $result->isError(). Must replace the result with an error according to problemWith() if !accepts($result->value()).
