Double-ended queue with stable indices

Implementations

Like VecDeque::with_capacity

Returns the element with index i, if it is still in the deque.

Panics on index overflow.

Panics on index overflow.

Panics on index overflow.

Panics on index overflow.

Removes the element with index i, by replacing it with the eleement from the front. Invalidates the index of the front element element (now i refers to that) but leaves other indices valid. Panics on index overflow.

Removes the element with index i, by replacing it with the eleement from the back. Invalidates the index of the back element (now i refers to that), but leaves other indices valid. Panics on index overflow.

The index of the first item the deque. If the queue is empty, this is the same as end_index.

The index just after the end of the qeue. I.e., the index that would be assigned to a new element added with push_back. Panics on index overflow.

I is how many more times pop_front has been called than push_back.

Modifying this invalidates all indices.

Allos access to the VecDeque inside this Deque

Mutable access to the VecDeque inside this Dequeu. Adding/removing elements at the front of of the VecDeque invalidates all indices.

Modifying the parts inconsistently will invalidate indices.

Use this to cast from one trait object type to another. Read more

Use this to upcast a trait to one of its supertraits. Read more

Use this to cast from one trait object type to another. This method is more customizable than the dyn_cast method. Here you can also specify the “source” trait from which the cast is defined. This can for example allow using casts from a supertrait of the current trait object. Read more

Use this to cast from one trait object type to another. With this method the type parameter is a config type that uniquely specifies which cast should be preformed. Read more

Returns the argument unchanged.

Instruments this type with the current Span, returning an Instrumented wrapper. Read more

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
