Trait Lit 

pub trait Lit: Sized + Sealed {
    // Required method
    fn parse(input: ParseStream<'_>) -> Result<Self>;
}

A value that can be parsed by this crate from a syn::Lit.

See set::lit and on::lit for usage examples.

This trait is sealed, and cannot be implemented for types outside this crate.

Required Methods

fn parse(input: ParseStream<'_>) -> Result<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.
