Struct RuntimeDiagnostics 

pub struct RuntimeDiagnostics { /* private fields */ }

An opt-in Runtime Diagnostics port.

The port only stores local, ephemeral, best-effort records. It never calls observer code and never waits for a consumer. It is therefore unsuitable for audit, durable Story correctness, persistence, replay, or redelivery.

Implementations

impl RuntimeDiagnostics

pub fn new() -> Self

Creates an empty diagnostics port with no observers.

pub fn subscribe( &self, filter: DiagnosticFilter, capacity: usize, ) -> Result<DiagnosticObserver, DiagnosticSubscribeError>

Adds an independently bounded, source-filtered observer queue.

pub fn subscribe_all( &self, capacity: usize, ) -> Result<DiagnosticObserver, DiagnosticSubscribeError>

Adds an all-source observer queue.

pub fn observer_count(&self) -> usize

Returns the number of observers that are still connected to this port.
