Trait Sampler 

Source 
pub trait Sampler: Send + Sync {
    // Required methods
    fn should_sample(
        &self,
        trace_id: &str,
        parent_sampled: Option<bool>,

Expand description

采样器 trait：根据 trace_id 与父 span 状态做出采样决策

Required Methods§

Source

fn should_sample( &self, trace_id: &str, parent_sampled: Option<bool>, ) -> SamplingDecision

做出采样决策

§参数
  • trace_id：trace 标识（32 字符 hex）
  • parent_sampled：父 span 是否已采样（None 表示根 span）
Source

fn name(&self) -> &'static str

采样器名称（用于可观测性）

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
