Trait ById 

pub trait ById {
    type Id;
    type Entry;
    type Error;

    // Required methods
    fn byid(&self, t: Self::Id) -> Result<&Self::Entry, Self::Error>;
    fn byid_mut(&mut self, t: Self::Id) -> Result<&mut Self::Entry, Self::Error>;
}

Required Associated Types

type Id

type Entry

type Error

Required Methods

fn byid(&self, t: Self::Id) -> Result<&Self::Entry, Self::Error>

fn byid_mut(&mut self, t: Self::Id) -> Result<&mut Self::Entry, Self::Error>

Dyn Compatibility

This trait is dyn compatible.

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