Struct apollo_encoder::ScalarDefinition

pub struct ScalarDefinition { /* private fields */ }

Represents scalar types such as Int, String, and Boolean. Scalars cannot have fields.

ScalarTypeDefinition: Description? scalar Name Directives?

Detailed documentation can be found in GraphQL spec.

Example

use apollo_encoder::ScalarDefinition;

let mut scalar = ScalarDefinition::new("NumberOfTreatsPerDay".to_string());
scalar.description(Some(
    "Int representing number of treats received.".to_string(),
));

assert_eq!(
    scalar.to_string(),
    r#""Int representing number of treats received."
scalar NumberOfTreatsPerDay
"#
);
