Struct RecorderHealth 

pub struct RecorderHealth(/* private fields */);

Available on crate feature dial9 only.

Recorder health for an application’s metrics exporter or diagnostics bundle. Pass sink to the upstream recorder builder’s metrics sink. Nothing is installed globally. Reading this handle performs no disk I/O. Create a fresh health handle for each recorder session.

The flush/processing threads update atomics; application event recording does no additional work. This consumes dial9 0.5’s metric field names and should be checked when upgrading dial9. It covers the counters listed here, not every upstream metric or every possible write failure.

Implementations

impl RecorderHealth

pub fn sink(&self) -> BoxEntrySink

pub fn snapshot(&self) -> RecorderHealthSnapshot

Trait Implementations

impl Clone for RecorderHealth

fn clone(&self) -> RecorderHealth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecorderHealth

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for RecorderHealth

fn default() -> RecorderHealth

Returns the “default value” for a type.

impl EntrySink<BoxEntry> for RecorderHealth

fn append(&self, entry: BoxEntry)

Append the entry to the in-memory buffer. Unless this is explicitly a test sink, the append() call must never block and must never panic. Test sinks are encouraged to immediately panic on invalid entries. Production sinks should emit a tracing event when invalid entries are found.

fn flush_async(&self) -> FlushWait

Request the sink to flush its contents to some sort of persistent storage. The returned FlushWait can be used to tell when the sink is flushed.

fn append_on_drop(&self, entry: E) -> AppendOnDrop<E, Self>

where Self: Sized + Clone,

Wrap entry in a smart pointer that will automatically append it to this sink when dropped.

fn append_on_drop_default(&self) -> AppendOnDrop<E, Self>

where Self: Sized + Clone, E: Default,
