Struct apollo_encoder::EnumDefinition

pub struct EnumDefinition { /* private fields */ }

Enums are special scalars that can only have a defined set of values.

EnumTypeDefinition: Description? enum Name Directives? EnumValuesDefinition?

Detailed documentation can be found in GraphQL spec.

Example

use apollo_encoder::{Argument, Directive, EnumValue, EnumDefinition, Value};

let mut enum_ty_1 = EnumValue::new("CAT_TREE".to_string());
enum_ty_1.description(Some("Top bunk of a cat tree.".to_string()));
let enum_ty_2 = EnumValue::new("BED".to_string());
let mut deprecated_directive = Directive::new(String::from("deprecated"));
deprecated_directive.arg(Argument::new(String::from("reason"), Value::String(String::from("Box was recycled."))));
let mut enum_ty_3 = EnumValue::new("CARDBOARD_BOX".to_string());
enum_ty_3.directive(deprecated_directive);

let mut enum_ = EnumDefinition::new("NapSpots".to_string());
enum_.description(Some("Favourite cat nap spots.".to_string()));
enum_.value(enum_ty_1);
enum_.value(enum_ty_2);
enum_.value(enum_ty_3);

assert_eq!(
    enum_.to_string(),
    r#""Favourite cat nap spots."
enum NapSpots {
  "Top bunk of a cat tree."
  CAT_TREE
  BED
  CARDBOARD_BOX @deprecated(reason: "Box was recycled.")
