Fixed-capacity audit ring.

Implementations

impl AuditRing

pub fn new(capacity: usize) -> Self

Creates a ring holding at most capacity entries.

Panics

Panics if capacity is zero.

pub fn set_observer(&mut self, observer: AuditObserver)

Installs observer, replacing any previous one. It sees every record appended from this point on, including records that are later overwritten before a host drains them.

Whether an observer is installed.

pub fn append(&mut self, record: AuditRecord) -> u64

Appends a record, overwriting the oldest entry when full, and returns the assigned sequence number.

pub fn oldest_retained(&self) -> Option<u64>

The oldest sequence number still retained.

pub fn next_sequence(&self) -> u64

The sequence number the next appended record will receive.

pub fn capacity(&self) -> usize

The fixed entry capacity, for capability reporting.

pub fn read(&self, cursor: u64, limit: usize) -> AuditPage

Reads at most limit entries with seq >= cursor, oldest first.
