Trait Deprecable 

pub trait Deprecable {
    const TYPE_NAME: &'static str;
    const MIN_SUPPORTED_APP_VERSION: &'static str;

    // Provided method
    fn error() -> DeprecatedVersionError { ... }
}

This trait should be implemented for types that have deprecated versions. You can then use them inside the dispatch enum by wrapping them into the Deprecated type.

Required Associated Constants

const TYPE_NAME: &'static str

const MIN_SUPPORTED_APP_VERSION: &'static str

Provided Methods

fn error() -> DeprecatedVersionError

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.
