ShadowHandle

autumn_web::shadow

Struct ShadowHandle 

Source 
pub struct ShadowHandle {
    pub registry: ShadowRegistry,
    pub enabled: bool,
    pub target: Option<String>,
}
Expand description

What {actuator-prefix}/shadow needs to report on a mirror run: the registry plus the two facts that live in config rather than in it.

Installed into crate::AppState’s runtime extension map when the mirror layer is assembled, so a replica with mirroring switched off simply has no handle and the endpoint reports a disabled mirror.

Fields§

§registry: ShadowRegistry

Shared counters and the bounded divergence ring.

§enabled: bool

Whether mirroring is switched on for this replica.

§target: Option<String>

The configured candidate target.

Implementations§

Source§

impl ShadowHandle

Source

pub fn snapshot(&self) -> ShadowSnapshot

Build the payload the actuator endpoint publishes.

Source

pub fn disabled_snapshot() -> ShadowSnapshot

The payload for a replica that never assembled a mirror.

Source

pub fn inactive(target: impl Into<String>) -> Self

A handle for a replica that configured [shadow] but could not assemble a mirror — today, a build without the http-client feature, which has no way to dial the candidate.

Installed so the actuator can distinguish “configured but inert here” from “never configured”: both report enabled: false, but only this one reports the target the operator asked for.
