Trait juniper::FromInputValue [−][src]
Parse an unstructured input value into a Rust data type.
The conversion can fail, and must in that case return None. Implemented
automatically by the convenience macro graphql_scalar! or by deriving GraphQLEnum.
Must be implemented manually when manually exposing new enums or scalars.
Required Methods
fn from_input_value(v: &InputValue) -> Option<Self>[−]
Performs the conversion.
