Attribute Macro graphql_enum 

#[graphql_enum]

Define a GraphQL enum type.

Generates a GraphQL Enum type definition from a Rust enum. Only unit variants (no fields) are supported.

Example

use server_less::graphql_enum;

#[graphql_enum]
#[derive(Clone, Debug)]
enum Status {
    /// User is active
    Active,
    /// User is inactive
    Inactive,
    /// Awaiting approval
    Pending,
}

// Then register with #[graphql]:
#[graphql(enums(Status))]
impl MyService {
    pub fn get_status(&self) -> Status { Status::Active }
}

Generated Methods

• __graphql_enum_type() -> async_graphql::dynamic::Enum - Enum type definition
• __to_graphql_value(&self) -> async_graphql::Value - Convert to GraphQL value

Variant Naming

Variant names are converted to SCREAMING_SNAKE_CASE for GraphQL:

• Active → ACTIVE
• InProgress → IN_PROGRESS
