Trait FromOffset

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

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

where U: ToOffset,

Dyn Compatibility

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
