Trait AstTypes 

pub trait AstTypes: Annotation {
    type Annotation: Annotation;
    type Literal: Annotation;
    type MacroId: Annotation + Hash + AsRef<str>;
    type Symbol: Annotation + Copy + Hash;
    type Path: Annotation;
}

Required Associated Types

type Annotation: Annotation

An annotation on an arbitrary Expr

type Literal: Annotation

A literal value

type MacroId: Annotation + Hash + AsRef<str>

A (possibly interned) symbol or index which implements AsRef<str>

type Symbol: Annotation + Copy + Hash

A (possibly interned) symbol or index

type Path: Annotation

A (possibly compound) symbol or index

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.
