Struct PressureObservation 

pub struct PressureObservation {
    pub adapter_id: String,
    pub adapter_version: Option<String>,
    pub observed_at_epoch_s: u64,
    pub model_name: Option<String>,
    pub total_tokens: Option<u64>,
    pub context_window_tokens: Option<u64>,
    pub context_used_pct: Option<u8>,
    pub compaction_signal: Option<bool>,
    pub usage: TokenUsage,
}

A neutral lifecycle-pressure observation extracted from harness telemetry. Carries everything a context.pressure_observed event or a receipt telemetry_summary needs, with no harness-private fields.

Wire-stable field names; Options are skip_serializing_if so absent signals stay absent on the wire (callers must not rely on null vs missing for these — they are not required-nullable).

Fields

adapter_id: String

Stable adapter id (matches AdapterManifest::adapter_id, e.g. "claude", "codex", "gemini", "opencode").

adapter_version: Option<String>

Adapter version when discoverable from the telemetry source.

observed_at_epoch_s: u64

Seconds since UNIX epoch at which this observation was sourced (typically the underlying log/session-file mtime).

model_name: Option<String>

Model identifier when surfaced by the telemetry source or env.

total_tokens: Option<u64>

Most recent prompt-side token count (window-relative).

context_window_tokens: Option<u64>

Adapter-reported context window in tokens.

context_used_pct: Option<u8>

Percentage of the context window consumed (0..=100), when both numerator and denominator are available.

compaction_signal: Option<bool>

Some(true) if the adapter signaled a compaction/compression event in the observed session window. None means “no signal” (not “definitely false”).

usage: TokenUsage

Granular usage breakdown, when the source provides it.

Trait Implementations

impl Clone for PressureObservation

fn clone(&self) -> PressureObservation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PressureObservation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PressureObservation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PressureObservation

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

impl Serialize for PressureObservation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
