Trait ConstBool

pub trait ConstBool {
    type Value: Sized;

    const VALUE: Self::Value;
}

Allows to convert compile-time constants into type-level booleans.

See also the const_bool macro, and the True and False types.

Required Associated Constants

const VALUE: Self::Value

The constant value of the type-level boolean.

Required Associated Types

type Value: Sized

The resulting type-level boolean (True or False).

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.
