Trait IntoLiteral 

pub trait IntoLiteral: Clone + 'static {
    type Output: Clone + PartialEq + Debug;

    // Required methods
    fn to_json_value(&self) -> Value;
    fn extract(value: &Value) -> Option<Self::Output>;
    fn display(&self) -> String;
}

Trait for types that can be used as literal values.

Required Associated Types

type Output: Clone + PartialEq + Debug

Required Methods

fn to_json_value(&self) -> Value

fn extract(value: &Value) -> Option<Self::Output>

fn display(&self) -> String

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
