Trait ClassToggle 

pub trait ClassToggle {
    // Required method
    fn to_class_toggle(&self) -> bool;
}

A trait which designates toggle types.

bool, Option, Result, and Fn types for them are supported.

When implementing it yourself, it should return a bool which is the truthy version of the value.

• Some(x) -> true
• Some(true) -> true
• Some(false) -> false
• None -> false

Required Methods

fn to_class_toggle(&self) -> bool

From ClassToggle.

Converts the type into a boolean.

• Some(x) -> true
• Some(true) -> true
• Some(false) -> false
• None -> false

Dyn Compatibility

This trait is dyn compatible.

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