Trait IntoValue 

pub trait IntoValue<S> {
    // Required method
    fn into_value(self) -> Value<S>;
}

Conversion into a Value.

This trait exists to work around orphan rules and allow to specify custom efficient conversions whenever some custom ScalarValue is involved (impl IntoValue<CustomScalarValue> for ForeignType would work, while impl From<ForeignType> for Value<CustomScalarValue> wound not).

This trait is used inside graphql_value! macro expansion and implementing it allows to put values of the implementor type there.

Required Methods

fn into_value(self) -> Value<S>

Converts this value into a Value.
