Implementations

impl<T: Debug> RingVec<T>[src]

pub fn new(capacity: usize) -> RingVec<T>[src]

Creates an empty RingVec

pub fn new_preallocated(capacity: usize) -> RingVec<T>[src]

Creates an empty RingVec with preallocated storage

pub fn is_full(&self) -> bool[src]

True if there is no spare capacity

pub fn len(&self) -> usize[src]

Returns the number of items in the RingVec

pub fn capacity(&self) -> usize[src]

Returns the maximum possible number of items.

pub fn peek(&self) -> Option<&T>[src]

Returns a ref to the head of the queue, if any.

pub fn pop(&mut self) -> Option<T>[src]

Returns the next item in the queue, if any.

pub fn push(&mut self, item: T) -> Result<(), T>[src]

Appends an item if there is space.

pub fn empty(&mut self)[src]

Empties the RingVec, optionally shrinking the storage.

pub fn shrink_to_fit(&mut self)[src]

Attempts to reduce memory usage.
