Struct RingBuffer 

pub struct RingBuffer<T, const N: usize> { /* private fields */ }

A fixed-size circular buffer for storing numerical samples.

Implementations

impl<T: Default + Copy, const N: usize> RingBuffer<T, N>

pub fn new() -> Self

Creates a new, empty ring buffer.

pub fn push(&mut self, value: T)

Pushes a new value into the buffer, overwriting the oldest if full.

pub fn count(&self) -> usize

Returns the number of elements currently in the buffer.

pub fn iter(&self) -> impl Iterator<Item = &T>

Returns an iterator over the values in chronological order (oldest to newest).

impl<const N: usize> RingBuffer<f32, N>

pub fn average(&self) -> f32

Calculates the arithmetic mean of the values in the buffer.

pub fn trend(&self) -> f32

Calculates the trend (slope) based on a simple linear regression or just the difference between first and last half. Returns positive if increasing, negative if decreasing.

pub fn variance(&self) -> f32

Calculates the variance (spread) of the values in the buffer.

Used for stutter detection: high variance in frame times indicates inconsistency.

pub fn min(&self) -> f32

Returns the minimum value in the buffer, or f32::MAX if empty.

pub fn max(&self) -> f32

Returns the maximum value in the buffer, or f32::MIN if empty.

Trait Implementations

impl<T: Clone, const N: usize> Clone for RingBuffer<T, N>

fn clone(&self) -> RingBuffer<T, N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug, const N: usize> Debug for RingBuffer<T, N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Default + Copy, const N: usize> Default for RingBuffer<T, N>

fn default() -> Self

Returns the “default value” for a type.
