👎Deprecated since 4.7.1: use push_front

pub fn push_back(&mut self, elem: T) -> Result<(), Error>

Appends an element to the deque. Errors if the new collection length will not fit the confinement requirements.

pub fn remove(&mut self, index: usize) -> Result<T, Error>

pub fn drain<R>(&mut self, range: R) -> Drain<'_, T>

where R: RangeBounds<usize>,

Removes the specified range from the deque in bulk, returning all removed elements as an iterator. If the iterator is dropped before being fully consumed, it drops the remaining removed elements.

The returned iterator keeps a mutable borrow on the queue to optimize its implementation.

Panics

Panics if the starting point is greater than the end point or if the end point is greater than the length of the deque.

Leaking

If the returned iterator goes out of scope without being dropped (due to [mem::forget], for example), the deque may have lost and leaked elements arbitrarily, including elements outside the range.

pub fn truncate(&mut self, len: usize)

Shortens the deque, keeping the first len elements and dropping the rest.

If len is greater or equal to the deque’s current length, this has no effect.

pub fn remove(&mut self, elem: &T) -> Result<bool, Error>

Removes an element from the set. Errors if the index exceeds the number of elements in the set, of if the new collection length will be less than the confinement requirement. Returns if the element was present in the set.

pub fn take(&mut self, elem: &T) -> Result<Option<T>, Error>

Removes an element from the set. Errors if the index exceeds the number of elements in the set, of if the new collection length will be less than the confinement requirement. Returns the removed element otherwise.

pub fn remove(&mut self, elem: &T) -> Result<bool, Error>

Removes an element from the set. Errors if the index exceeds the number of elements in the set, of if the new collection length will be less than the confinement requirement. Returns if the element was present in the set.

pub fn take(&mut self, elem: &T) -> Result<Option<T>, Error>

Removes an element from the set. Errors if the index exceeds the number of elements in the set, of if the new collection length will be less than the confinement requirement. Returns the removed element otherwise.

pub fn remove(&mut self, key: &K) -> Result<Option<V>, Error>

Removes an element from the map. Errors if the index exceeds the number of elements in the map, of if the new collection length will be less than the confinement requirement. Returns the removed value otherwise.

pub fn remove(&mut self, key: &K) -> Result<Option<V>, Error>

Removes an element from the map. Errors if the index exceeds the number of elements in the map, of if the new collection length will be less than the confinement requirement. Returns the removed value otherwise.
