Struct SamplingConfig 

#[non_exhaustive]
pub struct SamplingConfig {
    pub default_rate: f64,
    pub per_event: BTreeMap<String, f64>,
    pub always_log_at_or_above: Severity,
    pub tail_buffer_capacity: u16,
    pub honour_traceparent_sampled: bool,
}

Sampling config (spec 15 § 2 + spec 13 § 6).

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.

default_rate: f64

Default head-sample rate [0.0, 1.0]. 1.0 = keep everything.

per_event: BTreeMap<String, f64>

Per-event-name overrides. Key is full_name.

always_log_at_or_above: Severity

Severity floor that bypasses sampling.

tail_buffer_capacity: u16

Tail-on-error buffer capacity per obs::scope! frame.

honour_traceparent_sampled: bool

Honour W3C traceparent.sampled from inbound HTTP. Default true.
