Field argument container

Implementations

impl<'a, S> Arguments<'a, S> where
    S: ScalarValue
[src]

pub fn get<T>(&self, key: &str) -> Option<T> where
    T: FromInputValue<S>, 
[src]

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.
