Trait FromOffset 

pub trait FromOffset<T>
where
    T: Sized,
{
    // Required method
    fn from_offset<U: ToOffset>(&self, relative_index: U) -> Option<&T>;
}

Provide from_offset convenience method that allows negative offsets from the end of an array/vector and never extends beyond the array/vector bounds It returns Option<&T> in keeping with the default get() method and because the array or vector may still be empty

Required Methods

fn from_offset<U: ToOffset>(&self, relative_index: U) -> Option<&T>

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