Struct DiagnosticHandle 

pub struct DiagnosticHandle { /* private fields */ }

A handle for exposing diagnostics from a component.

Components assert a handle where artifact name is suitable, but not guaranteed, to be used a filename

Example:

DataspaceRegistry::try_current()?
    .assert(
        DiagnosticHandle::new("my_artifact.json", move || {
            serde_json::to_vec(&my_state).unwrap_or_default()
        }),
        "diag-my-component",
    );

Implementations

impl DiagnosticHandle

pub fn new( artifact_name: impl Into<String>, collect_fn: impl Fn() -> Vec<u8> + Send + Sync + 'static, ) -> Self

Creates a new handle with the given artifact name and collection closure. collect_fn must run synchronously and reasonably fast to produce artifact bytes as it can delay entire diagnostic response

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 DiagnosticHandle

fn clone(&self) -> DiagnosticHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.
