Struct sentry_core::Span

pub struct Span { /* private fields */ }

A running Performance Monitoring Span.

The span needs to be explicitly finished via Span::finish, otherwise it will not be sent to Sentry.

Implementations

impl Span

pub fn set_data(&self, key: &str, value: Value)

Set some extra information to be sent with this Transaction.

pub fn data(&self) -> Data<'_>

Returns a smart pointer to the span’s data field.

Since Data implements Deref and DerefMut, this can be used to read and mutate the span data.

Concurrency

In order to obtain any kind of reference to the data field, a Mutex needs to be locked. The returned Data holds on to this lock for as long as it lives. Therefore you must take care not to keep the returned Data around too long or it will never relinquish the lock and you may run into a deadlock.

pub fn get_trace_context(&self) -> TraceContext

Get the TransactionContext of the Span.

Note that this clones the underlying value.

pub fn get_status(&self) -> Option<SpanStatus>

Get the status of the Span.

pub fn set_status(&self, status: SpanStatus)

Set the status of the Span.

pub fn set_request(&self, request: Request)

Set the HTTP request information for this Span.

pub fn iter_headers(&self) -> TraceHeadersIter

Returns the headers needed for distributed tracing.

pub fn finish(self)

Finishes the Span.

This will record the end timestamp and add the span to the transaction in which it was started.

pub fn start_child(&self, op: &str, description: &str) -> Span

Starts a new child Span with the given op and description.

The span must be explicitly finished via Span::finish.
