Enum SetParentError 

pub enum SetParentError {
    LayerNotFound,
    AlreadyStarted,
    SpanDisabled,
}

An error returned if OpenTelemetrySpanExt::set_parent could not set the parent.

Variants

LayerNotFound

The layer could not be found and therefore the action could not be carried out. This can happen with some advanced layers that do not handle downcasting well, for example [tracing_subscriber::reload::Layer].

AlreadyStarted

The span has been already started.

Someone already called a context-starting method such as OpenTelemetrySpanExt::context or the span has been entered and automatic context starting was not configured out.

SpanDisabled

The span is filtered out by tracing filters.

If the filtered out span had children, they will not be connected to the parent span either.

Trait Implementations

impl Debug for SetParentError

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
