Trait Type 

pub trait Type {
    const TYPE: &'static Type<'static>;
}

Type introspection.

This trait provides type metadata for Rust types, mapping them to their corresponding IDL representation. Implementing this trait allows a type to participate in Varlink’s type introspection system.

Usage

For custom types, use the Type derive macro:

use zlink::introspect::Type;

#[derive(Type)]
struct MyRequest {
    id: String,
    count: i32,
}

The derive macro automatically generates the appropriate Type implementation based on your struct’s fields.

Required Associated Constants

const TYPE: &'static Type<'static>

The type information.

Dyn Compatibility

This trait is not dyn compatible.

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