Trait index_set::FromIndex

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

Implemented for types that can be fully constructed from their indices.

Calling from_index on an index that was created by calling ToIndex::to_index on a value must return the original value.

Required methods

fn from_index(index: Self::Index) -> Option<Self>

Returns the value that has the given index, or None if the index is invalid.
