Struct RingStats 

pub struct RingStats<const N: usize> { /* private fields */ }

Fixed-size ring buffer of u32 samples. push overwrites the oldest entry once full – the only state this holds is values/len/next, all stack-sized by the const generic N, so a profiler holding several of these never allocates past its own construction.

Implementations

impl<const N: usize> RingStats<N>

pub fn push(&mut self, value: u32)

pub fn stats(&self) -> Distribution

Nearest-rank percentiles over whatever the ring currently holds. Percentiles do not care about chronological order, so this sorts a stack-local COPY of the valid slice (values is [u32; N], Copy because u32 is Copy – never a heap allocation) rather than the ring itself, which must keep its own write position intact for the next push.

Trait Implementations

impl<const N: usize> Clone for RingStats<N>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const N: usize> Debug for RingStats<N>

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

Formats the value using the given formatter.

impl<const N: usize> Default for RingStats<N>

fn default() -> Self

Returns the “default value” for a type.
