Crate singlevec

SingleVec is Vec-like container type optimized for storing a single item.

0 or 1 items are stored internally as a standard Option - which can be kept on the stack - but falls back to a standard Vec for multiple items - which are stored on the heap.

Although SingleVec shares many of the same traits and methods as Vec, it also shares many of the same methods as Option and Iterator where appropriate. Since only a single optional item is intended to be the common case, those methods can avoid iteration altogether.

Other Features

• serde provides Serialize and Deserialize support, provided that the inner type also has the same implementation.
