Trait cynic::QueryFragment

pub trait QueryFragment<'de>: Deserialize<'de> {
    type SchemaType;
    type Variables: QueryVariables;

    const TYPE: Option<&'static str> = None;

    fn query(builder: SelectionBuilder<'_, Self::SchemaType, Self::Variables>);
}

Indicates that a type may be used as part of a graphql query.

This will usually be derived, but can be manually implemented if required.

Required Associated Types

type SchemaType

The type in a schema that this QueryFragment represents

type Variables: QueryVariables

The variables that are required to execute this QueryFragment

Provided Associated Constants

const TYPE: Option<&'static str> = None

The name of the type in the GraphQL schema

Required Methods

fn query(builder: SelectionBuilder<'_, Self::SchemaType, Self::Variables>)

Adds this fragment to the query being built by builder
