Struct StatusSnapshot 

pub struct StatusSnapshot {
    pub schema_version: u16,
    pub observed_at_unix_ms: u64,
    pub sample_interval_ms: u64,
    pub capabilities: MetricCapabilities,
    pub system: SystemIdentity,
    pub cpu: CpuMetrics,
    pub load: LoadAverage,
    pub memory: MemoryMetrics,
    pub swap: SwapMetrics,
}

Top-level daemon snapshot returned by the status endpoint.

Every numeric field uses raw units. CPU and memory percentages are reported in the closed interval 0.0..=100.0. Bytes are unsigned 64-bit counts. observed_at_unix_ms is the Unix epoch in milliseconds at which the underlying counters were sampled.

CPU percentage values are derived from sampling-interval deltas, not from instantaneous single reads, so a freshly started daemon may legitimately report a snapshot whose CPU usage is still unknown. Such snapshots surface through the HealthResponse instead of through this endpoint.

Fields

schema_version: u16

Schema major version. Must equal crate::SCHEMA_VERSION_V1 for this endpoint.

observed_at_unix_ms: u64

Unix epoch in milliseconds at which the snapshot was produced.

sample_interval_ms: u64

Sampling cadence in milliseconds used to derive percentage metrics.

capabilities: MetricCapabilities

Per-metric capability flags.

system: SystemIdentity

Stable identity fields reported separately so clients can degrade by width priority.

cpu: CpuMetrics

CPU utilization, with optional Linux aggregate I/O wait.

load: LoadAverage

One-, five-, and fifteen-minute load averages.

memory: MemoryMetrics

Physical memory utilization.

swap: SwapMetrics

Swap utilization.

Implementations

impl StatusSnapshot

pub fn validate(&self) -> Result<(), Vec<ValidationViolation>>

Validate that every field satisfies the version-1 protocol invariants.

The returned ValidationViolation list is structured so callers can log individual fields and decide whether to reject the snapshot, surface it as a warning, or fall back to a warming-up health response.

Invariants

• schema_version == SCHEMA_VERSION_V1.
• observed_at_unix_ms > 0 and sample_interval_ms > 0.
• cpu.logical_cores > 0.
• All percentages are finite and in 0.0..=100.0.
• used_bytes <= total_bytes for memory and swap.
• When total_bytes == 0, the corresponding usage_pct is 0.0.
• iowait_pct is None exactly when cpu_iowait capability is false. A true capability with None is rejected because a Ready snapshot must report every supported metric.
