Struct QueryContext 

pub struct QueryContext {
    pub workflow_id: Option<String>,
    pub run_id: Option<String>,
    pub workflow_type: String,
    pub run_status: Option<String>,
    /* private fields */
}

Immutable state supplied to a registered query handler.

This context intentionally exposes no activity, signal-wait, or command APIs. Query handlers inspect committed history and return a value; query completion does not append an event or advance deterministic execution.

Fields

workflow_id: Option<String>

run_id: Option<String>

workflow_type: String

run_status: Option<String>

Implementations

impl QueryContext

pub fn workflow_input(&self) -> &Value

The normalized argument list used to start the workflow.

pub fn history_events(&self) -> &[HistoryEvent]

The immutable committed history used for this query snapshot.

pub fn signal_events(&self) -> &[QuerySignal]

All decoded signals in committed workflow order.

pub fn signals(&self, signal_name: &str) -> Vec<Vec<Value>>

Decoded argument lists for each committed signal with signal_name.
