Trait GenericsExt 

pub trait GenericsExt {
    // Required methods
    fn declared_lifetimes(&self) -> LifetimeSet;
    fn declared_type_params(&self) -> IdentSet;
}

Extension trait for pulling specific generics data from a generics AST representation.

Required Methods

fn declared_lifetimes(&self) -> LifetimeSet

Get the set of all lifetimes declared by the syntax element. This does not look for usage of the lifetime; see UsesLifetimes for that.

fn declared_type_params(&self) -> IdentSet

Get the set of all type parameters declared by the syntax element. This does not look for usage of the type parameter; see UsesTypeParams for that.

Dyn Compatibility

This trait is dyn compatible.

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