Implementations

impl DiagnosticState

pub fn new(name: impl Into<String>) -> Self

Create a new diagnostic state.

pub fn record_outgoing_request( &self, request_id: u64, method_id: u64, args: Option<HashMap<String, String>>, )

Record an outgoing request (we’re calling remote).

pub fn record_incoming_request( &self, request_id: u64, method_id: u64, args: Option<HashMap<String, String>>, )

Record an incoming request (remote is calling us).

pub fn complete_request(&self, request_id: u64)

Mark a request as completed.

pub fn record_channel_open( &self, channel_id: u64, direction: ChannelDirection, request_id: Option<u64>, )

Record a channel being opened.

pub fn record_channel_close(&self, channel_id: u64)

Record a channel being closed.

pub fn associate_channels_with_request( &self, channel_ids: &[u64], request_id: u64, )

Associate channels with a request (called after channels are opened but before request is sent).

pub fn add_custom_diagnostic<F>(&self, callback: F)

where F: Fn(&mut String) + Send + Sync + 'static,

Add a custom diagnostic callback.

pub fn dump_if_nonempty(&self) -> Option<String>

Dump this state if non-empty, returning None if there’s nothing to report. Uses try_read() to avoid deadlocking when called from signal handlers. Output is compact: single line for summary, one line per request.
