Trait cynic::variables::QueryVariables

pub trait QueryVariables {
    type Fields: QueryVariablesFields;

    const VARIABLES: &'static [(&'static str, VariableType)];
}

Allows a struct to be used as variables in a GraphQL query.

Users should not implement this themselves, and should use the QueryVariables derive. All the fields on a QueryVariables struct should be available as variables in the query, using $variable_name notation.

Required Associated Types

type Fields: QueryVariablesFields

A struct that determines which variables are available when using this struct.

Required Associated Constants

const VARIABLES: &'static [(&'static str, VariableType)]

An associated constant that contains the variable names & their types.

This is used to construct the query string we send to a server.

Object Safety

This trait is not object safe.
