Struct opentelemetry::sdk::trace::Config

pub struct Config {
    pub sampler: Box<dyn ShouldSample>,
    pub id_generator: Box<dyn IdGenerator>,
    pub span_limits: SpanLimits,
    pub resource: Option<Arc<Resource>>,
}

This is supported on crate feature trace only.

Tracer configuration

Fields

sampler: Box<dyn ShouldSample>

The sampler that the sdk should use

id_generator: Box<dyn IdGenerator>

The id generator that the sdk should use

span_limits: SpanLimits

span limits

resource: Option<Arc<Resource>>

Contains attributes representing an entity that produces telemetry.

Implementations

impl Config

pub fn with_sampler<T: ShouldSample + 'static>(self, sampler: T) -> Self

Specify the sampler to be used.

pub fn with_id_generator<T: IdGenerator + 'static>(
    self,
    id_generator: T
) -> Self

Specify the id generator to be used.

pub fn with_max_events_per_span(self, max_events: u32) -> Self

Specify the number of events to be recorded per span.

pub fn with_max_attributes_per_span(self, max_attributes: u32) -> Self

Specify the number of attributes to be recorded per span.

pub fn with_max_links_per_span(self, max_links: u32) -> Self

Specify the number of events to be recorded per span.

pub fn with_max_attributes_per_event(self, max_attributes: u32) -> Self

Specify the number of attributes one event can have.

pub fn with_max_attributes_per_link(self, max_attributes: u32) -> Self

Specify the number of attributes one link can have.

pub fn with_span_limits(self, span_limits: SpanLimits) -> Self

Specify all limit via the span_limits

pub fn with_resource(self, resource: Resource) -> Self

Specify the attributes representing the entity that produces telemetry

pub fn with_no_resource(self) -> Self

Use empty resource instead of default resource in this config.

Usually if no resource is provided, SDK will assign a default resource to the TracerProvider, which could impact the performance. Performance sensitive application can use function to disable such behavior and assign no resource to TracerProvider.

Trait Implementations

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Create default global sdk configuration.
