Trait ApiStability 

pub trait ApiStability {
    const STABILITY: StabilityLevel;
    const INTRODUCED_IN: Option<&'static str> = None;
    const STABILIZED_IN: Option<&'static str> = None;
    const DEPRECATED_IN: Option<&'static str> = None;
}

Trait to mark API stability level for types and functions

Required Associated Constants

const STABILITY: StabilityLevel

The stability level of this API component

Provided Associated Constants

const INTRODUCED_IN: Option<&'static str> = None

Optional version when this API was introduced

const STABILIZED_IN: Option<&'static str> = None

Optional version when this API was stabilized (if applicable)

const DEPRECATED_IN: Option<&'static str> = None

Optional deprecation information

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.
