[−][src]Trait cynic::IntoArgument

pub trait IntoArgument<T> {
    type Output: SerializableArgument;
    fn into_argument(self) -> Self::Output;
}

IntoArgument is used to type-check arguments to queries in cynic.

A GraphQL argument that accepts String! will accept any type that is IntoArgument<String>. Similarly, an optional String in GraphQL will accept any IntoArgument<Option<String>>.

There are implementations of this for most of the built in scalars to allow users to express arguments in a simple manner. The cynic::Enum derive also generates impls for converting options & refs easily.
