Trait Lit

pub trait Lit: Sized + Sealed {
    const SELF: Self;
    const NAME: &'static RefStr;

    // Provided method
    fn from_component(c: &Component<'_>) -> Option<Self> { ... }
}

A literal RefStr.

Types implementing Lit must be name::Components, and provide a conversion from a component iff the component’s RefStr representation is equal to Lit::NAME. Because these morphisms can only be guaranteed axiomatically, the trait can not currently be implemented by types outside of this crate.

Lit types are useful for efficiently creating known-valid Qualified refs, and sometimes for pattern matching.

Required Associated Constants

const SELF: Self

const NAME: &'static RefStr

Provided Methods

fn from_component(c: &Component<'_>) -> Option<Self>

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.
