Trait Variable

pub trait Variable {
    const TYPE: VariableType;
}

Used to determine the type of a given variable that appears in an argument struct.

Required Associated Constants

const TYPE: VariableType

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.
