Trait Basic 

pub trait Basic: Type {
    const SIGNATURE_CHAR: char;
    const SIGNATURE_STR: &'static str;

    // Provided method
    fn alignment(format: Format) -> usize { ... }
}

Trait for basic types.

All basic types are also Type implementers.

Required Associated Constants

const SIGNATURE_CHAR: char

The type signature, as a character.

const SIGNATURE_STR: &'static str

The type signature, as a string.

Provided Methods

fn alignment(format: Format) -> usize

The required padding alignment for the given format.

The default implementation covers all possible cases so you should never need to override it.

Dyn Compatibility

This trait is not dyn compatible.

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