Implementations

impl RecordBuffer

pub fn new() -> Self

Construct with the default capacities.

pub fn with_caps(per_ring: usize, max_rings: usize) -> Self

Construct with explicit per-ring and distinct-name caps.

pub fn record(&mut self, name: &str, bytes: Vec<u8>)

Record bytes under the named ring; oldest entry evicted when capacity reached. New ring names past max_rings are dropped with the name_drops counter ticking.

pub fn snapshot(&self, name: &str) -> Vec<Vec<u8>>

Read the current contents of the named ring.

pub fn name_drops(&self) -> u64

Cumulative drop count for unknown-name overflows.
