Struct Config

#[non_exhaustive]
pub struct Config {
    pub sampler: Box<dyn ShouldSample>,
    pub id_generator: Box<dyn IdGenerator>,

    pub resource: Cow<'static, Resource>,
}

Available on crate feature trace only.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

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: Cow<'static, Resource>

Contains attributes representing an entity that produces telemetry.

Implementations
