Struct RingBuffer 

pub struct RingBuffer { /* private fields */ }

A fixed-capacity circular buffer of ProbeResults.

When the buffer is full, the oldest entry is evicted.

Implementations

impl RingBuffer

pub fn new(capacity: usize) -> Self

Create a new ring buffer with the given capacity.

pub fn push(&mut self, result: ProbeResult)

Push a new probe result, evicting the oldest if at capacity.

pub fn snapshot(&self) -> Vec<ProbeResult>

Return a snapshot of all current samples as a Vec. This is a clone — callers get their own data and the lock is released as soon as the borrow ends.

pub fn len(&self) -> usize

How many samples are currently stored.

pub fn is_empty(&self) -> bool

True if the buffer contains no samples.

pub fn capacity(&self) -> usize

Current capacity.
