Trait Peek

pub trait Peek {
    // Required method
    fn peek(p: &mut Peeker<'_>) -> bool;
}

Implemented by tokens that can be peeked for.

Required Methods

fn peek(p: &mut Peeker<'_>) -> bool

Peek the parser for the given token.

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.
