Struct HotGate 

pub struct HotGate { /* private fields */ }

The hot-path verbosity gate — a per-plugin atomic the tracer publishes and the sync grammar trampoline reads once per guest call (design §4: “a single relaxed-atomic per-plugin gate load and a predicted-not-taken branch when off”). The Arc<AtomicU8> is owned by the PluginTracer (its single source of truth for verbosity) and cloned into the trampoline; a :set plugin.trace-level write updates the atomic, so the very next keystroke reads the new level with no lock and no cross-plugin cost.

Implementations

impl HotGate

pub fn level(&self) -> TraceLevel

The current effective gate level — the relaxed hot-path load.

pub fn records_calls(&self) -> bool

Will a per-call success record (emitted at Debug) be kept? The hot-path predicate: false at the default Info gate, so the trampoline does zero timing / allocation / formatting on the common keystroke.

pub fn disabled() -> Self

A permanently-off gate for the no-tracer paths (tests / benches) — reads as Off, so records_calls() is always false.

Trait Implementations

impl Clone for HotGate

fn clone(&self) -> HotGate

Returns a duplicate of the value.

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

Performs copy-assignment from source.
