Struct CircularBuffer 

pub struct CircularBuffer<T> { /* private fields */ }

A fixed-size circular buffer that automatically evicts the oldest items when the buffer is full. Useful for maintaining a rolling window of data.

Implementations

impl<T> CircularBuffer<T>

pub fn new(capacity: usize) -> Self

Create a new circular buffer with the given capacity.

pub fn add(&mut self, item: T)

Add an item to the buffer. If the buffer is full, the oldest item will be evicted.

pub fn add_all(&mut self, items: impl IntoIterator<Item = T>)

Add multiple items to the buffer at once.

pub fn get_recent(&self, count: usize) -> Vec<&T>

Get the most recent N items from the buffer. Returns fewer items if the buffer contains less than N items.

pub fn to_vec(&self) -> Vec<&T>

Get all items currently in the buffer, in order from oldest to newest.

pub fn clear(&mut self)

Clear all items from the buffer.

pub fn len(&self) -> usize

Get the current number of items in the buffer.

pub fn is_empty(&self) -> bool

Check if the buffer is empty.

Trait Implementations

impl<T: Clone> Clone for CircularBuffer<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
