Struct OpenTelemetry 

pub struct OpenTelemetry<T> { /* private fields */ }

Available on crate feature opentelemetry only.

OpenTelemetry extension

Example

use async_graphql_extras::OpenTelemetry;

let tracer = todo!("create your OpenTelemetry tracer");

let schema = Schema::build(Query, EmptyMutation, EmptySubscription)
    .extension(OpenTelemetry::new(tracer))
    .finish();

Implementations

impl<T> OpenTelemetry<T>

pub fn new(tracer: T) -> OpenTelemetry<T>

where T: Tracer + Send + Sync + 'static, <T as Tracer>::Span: Sync + Send,

Use tracer to create an OpenTelemetry extension.

pub fn with_trace_scalars(self, trace_scalars: bool) -> Self

Enable or disable tracing for scalar and enum field resolutions.

When false (the default), spans are not created for fields that return scalar or enum types. This significantly reduces the number of spans generated, preventing span explosion in queries with many scalar fields.

When true, spans are created for all field resolutions, including scalars and enums.

Example

use async_graphql::extensions::OpenTelemetry;
use async_graphql_extras::OpenTelemetry as ExtrasOpenTelemetry;

let tracer = todo!("create your OpenTelemetry tracer");

// Trace all fields including scalars
let schema = Schema::build(Query, EmptyMutation, EmptySubscription)
    .extension(ExtrasOpenTelemetry::new(tracer).with_trace_scalars(true))
    .finish();

Trait Implementations

fn create(&self) -> Arc<dyn Extension>
