Struct DatadogSampler 

pub struct DatadogSampler { /* private fields */ }

A composite sampler that applies rules in order of precedence

Implementations

impl DatadogSampler

pub fn new(rules: Vec<SamplingRule>, rate_limit: i32) -> Self

Creates a new DatadogSampler with the given rules

pub fn on_agent_response(&self) -> Box<dyn for<'a> Fn(&'a str) + Send + Sync>

pub fn on_rules_update(&self) -> SamplingRulesCallback

Creates a callback for updating sampling rules from remote configuration.

Returns

A boxed function that takes a slice of SamplingRuleConfig and updates the sampling rules.

pub fn sample(&self, data: &impl SamplingData) -> DdSamplingResult

Sample an incoming span based on the parent context and attributes.

If a parent sampling decision is present it is inherited; otherwise the root-span sampling pipeline is run via Self::sample_root.
