Trait JsonSchema 

pub trait JsonSchema {
    // Required method
    fn json_schema() -> String;

    // Provided method
    fn is_optional() -> bool { ... }
}

A type with a JSON Schema.

Required Methods

fn json_schema() -> String

The schema, as a JSON object.

Provided Methods

fn is_optional() -> bool

true when a struct field of this type may be left out (Option).

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
