only.Expand description
Types that can create instances of Tracer
.
Associated Types
Required methods
Returns a new versioned tracer with a given name.
The name
should be the application name or the name of the library
providing instrumentation. If the name is empty, then an
implementation-defined default name may be used instead.
Examples
use opentelemetry::{global, trace::TracerProvider};
let provider = global::tracer_provider();
// tracer used in applications/binaries
let tracer = provider.tracer("my_app");
// tracer used in libraries/crates that optionally includes version and schema url
let tracer = provider.versioned_tracer(
"my_library",
Some(env!("CARGO_PKG_VERSION")),
Some("https://opentelemetry.io/schema/1.0.0")
);
fn force_flush(&self) -> Vec<TraceResult<()>>
fn force_flush(&self) -> Vec<TraceResult<()>>
Force flush all remaining spans in span processors and return results.
