Trait Get 

pub trait Get {
    type Error;
    type Input;
    type Output<'output>
       where Self: 'output;

    // Required method
    fn get(&self, input: Self::Input) -> Result<Self::Output<'_>, Self::Error>;
}

Required Methods

fn get(&self, input: Self::Input) -> Result<Self::Output<'_>, Self::Error>

Returns an immutable inner reference of a derived element.

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.
