pub fn get<T>(&self, key: &str) -> Option<T> where
T: FromInputValue<S>,
Get and convert an argument into the desired type.
If the argument is found, or a default argument has been provided,
the InputValue
will be converted into the type T
.
Returns Some
if the argument is present and type conversion
succeeeds.
