Struct Probe

Source

pub struct Probe { /* private fields */ }

Expand description

Probe API. All methods are no-ops without the probe feature.

Implementations§

Source §

impl Probe

Source

pub fn span(name: &'static str) -> Span

Open a timed span. The returned guard records its name + nanos on drop into the thread-local event buffer.

Source

pub fn sample_rss(label: &'static str, bytes: u64)

Record an RSS checkpoint with the given label + byte count. The caller supplies the bytes (this module does not depend on platform RSS readers) so consumers can use whatever measurement helper they own.

Source

pub fn drain() -> Vec<Event>

Drain the per-thread event buffer.

Source

pub fn drop_events()

Discard the per-thread event buffer without allocating a Vec to hand back. Used by long-running harnesses (e.g. AZ_E2E_TEST) that want to prevent the thread-local buffer from inflating RSS during thousands of layout passes without actually needing the events.

Source

pub fn peek_len() -> usize

Current number of events in the per-thread buffer. Cheap to call.

Source

pub fn enabled() -> bool

Whether the probe feature is compiled in.
