Trait Alphabet

pub trait Alphabet: Display {
    // Required methods
    fn nothing() -> Self;
    fn any(&self) -> bool;
}

Trait for input/output alphabet. Used for internal enum generation.

All the input structs are enumerated in an internal enum that implements this trait.

Required Methods

fn nothing() -> Self

Return a value that represents no input/output.

fn any(&self) -> bool

Check if the alphabet is anything other than nothing.

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.
