Struct SpawnerHandle 

pub struct SpawnerHandle {
    pub session_id: String,
    pub context_id: String,
    pub delegation_id: String,
    pub report_to: Option<CompletionAddress>,
}

The value injected into the child: a Spawner plus the delegation id the launcher minted.

Fields

session_id: String

context_id: String

delegation_id: String

report_to: Option<CompletionAddress>

Implementations

impl SpawnerHandle

pub fn for_delegation(spawner: &Spawner, delegation_id: String) -> Self

The handle for one launch of spawner’s child.

pub fn to_env_value(&self) -> String

The compact JSON written into SPAWNER_ENV.

A lineage-only handle carries the three keys that name the relationship and nothing that could be read as an address; a reporting one adds url.

pub fn from_env() -> Result<Option<Self>, RuntimeError>

This process’s own handle, read from SPAWNER_ENV.

Ok(None) for a capsule nobody delegated — the variable absent, or blank. A variable that is set to something else is an error and not an absence: a child that cannot read its spawner cannot record which session spawned it or report to it, and running it anyway would produce work whose provenance and outcome reach nobody.

pub fn parse(value: &str) -> Result<Self, RuntimeError>

Parse one Self::to_env_value string.
