Trait ChainableExtensions 

pub trait ChainableExtensions {
    // Required methods
    fn contains<T>(&self) -> bool
       where T: Extension;
    fn get_ref<T>(&self) -> Option<&T>
       where T: Extension;
    fn get_arc<T>(&self) -> Option<Arc<T>>
       where T: Extension;
}

Required Methods

fn contains<T>(&self) -> bool

where T: Extension,

fn get_ref<T>(&self) -> Option<&T>

where T: Extension,

fn get_arc<T>(&self) -> Option<Arc<T>>

where T: Extension,

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.
