Struct GenSpec 

pub struct GenSpec {
    pub origin: String,
    pub producer: Option<String>,
    pub subject: Option<String>,
    pub vars: Vec<(String, String)>,
    pub rate_hz: Option<f64>,
    pub pattern: GenPattern,
    pub duration: Duration,
    pub seed: u64,
    pub tool: String,
    pub faults: Vec<Fault>,
}

Available on crate feature decode only.

What to generate.

Fields

origin: String

The origin chunk the generated keys claim (h-…). Stated, printed, and stamped into the marker — impersonation is the feature, and the marker is what keeps it honest.

producer: Option<String>

Only this producer’s subjects (else: every host producer in the set).

subject: Option<String>

Only subjects whose declared path contains this.

vars: Vec<(String, String)>

{var} values by name; unnamed vars get deterministic synthetic values (stated in the plan).

rate_hz: Option<f64>

Override every entry’s rate (Hz). None = the registry-driven defaults: telemetry 1 Hz, state ttl/2 refresh, events inside their declared budget.

pattern: GenPattern

duration: Duration

seed: u64

Drives synthesis and jitter — same seed, same run.

tool: String

The tool name stamped into the marker.

faults: Vec<Fault>

Fault kinds to inject (#163). Empty = conforming traffic. Non-empty expands the plan to one variant per (subject × fault), each carrying a single fault=<kind> marker and a printable delta — double-guarded at the CLI edge (--i-know plus an explicit endpoint/--base).

Trait Implementations

impl Clone for GenSpec

fn clone(&self) -> GenSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GenSpec

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

Formats the value using the given formatter.
