Enum SamplingDecision 

#[non_exhaustive]
pub enum SamplingDecision {
    Drop,
    Keep,
    ParentSet {
        sampled: bool,
    },
}

Outcome of the head-sampler decision.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Drop

The envelope is dropped before reaching the worker.

Keep

The envelope is kept under the local rate (or severity floor).

ParentSet

The decision was forced by an upstream traceparent.sampled; the emitter should stamp SAMPLING_REASON_OVERRIDE.

Fields

sampled: bool

Whether the parent decided to sample.

Trait Implementations

impl Clone for SamplingDecision

fn clone(&self) -> SamplingDecision

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SamplingDecision

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

Formats the value using the given formatter.

impl PartialEq for SamplingDecision

fn eq(&self, other: &SamplingDecision) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
