Struct DiagnosticCollector 

pub struct DiagnosticCollector { /* private fields */ }

A named, on-demand producer of diagnostic artifact bytes.

A collector pairs an artifact name with a synchronous closure that produces the artifact’s bytes when invoked. Collectors are registered through a DiagnosticsEmitter and gathered on demand by whichever subsystem is responsible for assembling diagnostic artifacts.

The artifact name is suitable, but not guaranteed, to be used as a filename.

Implementations

impl DiagnosticCollector

pub fn new<T>( artifact_name: impl Into<String>, collect_fn: impl Fn() -> T + Send + Sync + 'static, ) -> Self

where T: Into<Vec<u8>>,

Creates a new collector with the given artifact name and collection closure.

collect_fn runs synchronously and must return promptly, as it can delay the collection of artifacts for the whole system.

pub fn artifact_name(&self) -> &str

Returns the artifact name.

pub fn collect(&self) -> Vec<u8>

Collects and returns the artifact bytes.

Trait Implementations

impl Clone for DiagnosticCollector

fn clone(&self) -> DiagnosticCollector

Returns a duplicate of the value.

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

Performs copy-assignment from source.
