Struct TraceSampling 

pub struct TraceSampling {
    pub dropped_trace: bool,
    pub priority: Option<i32>,
    pub decision_maker: Option<MetaString>,
    pub otlp_sampling_rate: Option<MetaString>,
}

Trace-level sampling metadata.

This struct stores sampling-related metadata that applies to the entire trace, typically set by the trace sampler and consumed by the encoder.

Fields

dropped_trace: bool

Whether or not the trace was dropped during sampling.

priority: Option<i32>

The sampling priority assigned to this trace.

Common values include:

• 2: Manual keep (user-requested)
• 1: Auto keep (sampled in)
• 0: Auto drop (sampled out)
• -1: Manual drop (user-requested drop)

decision_maker: Option<MetaString>

The decision maker identifier indicating which sampler made the sampling decision.

Common values include:

• -9: Probabilistic sampler
• -4: Errors sampler
• None: No decision maker set

otlp_sampling_rate: Option<MetaString>

The OTLP sampling rate applied to this trace, formatted as a string (e.g., “0.25”).

This corresponds to the _dd.otlp_sr tag and represents the effective sampling rate from the OTLP ingest path.

Implementations

impl TraceSampling

pub fn new( dropped_trace: bool, priority: Option<i32>, decision_maker: Option<MetaString>, otlp_sampling_rate: Option<MetaString>, ) -> Self

Creates a new TraceSampling instance.

Trait Implementations

impl Clone for TraceSampling

fn clone(&self) -> TraceSampling

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceSampling

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

Formats the value using the given formatter.

impl PartialEq for TraceSampling

fn eq(&self, other: &TraceSampling) -> 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.
