Trait contiguous_map::TryFromIndex

pub trait TryFromIndex: ToIndex where
    Self: Sized, {
    fn try_from_index(index: Self::Index) -> Option<Self>;
}

Trait to convert an index that implements the Key trait to a different type.

This can be implemented in combination with ToIndex to enable a blanket implementation of the Key trait.
