Trait opentelemetry::api::trace::tracer::TracerGenerics

pub trait TracerGenerics: Tracer {
    fn with_span<T, F>(&self, name: &'static str, f: F) -> T
    where
        F: FnOnce(&mut Self::Span) -> T;
}

TracerGenerics are functions that have generic type parameters. They are a separate trait so that Tracer can be used as a trait object in GlobalTracer.

Required methods

fn with_span<T, F>(&self, name: &'static str, f: F) -> T where
    F: FnOnce(&mut Self::Span) -> T, 

Wraps the execution of the function body with a span. It starts a new span and sets it as the active span for the given function. It then executes the body. It closes the span before returning the execution result.
