Struct ExecContext 

pub struct ExecContext { /* private fields */ }

Execution context — holds runtime variables for a single execution unit.

Implementations

impl ExecContext

pub fn new(flow_name: &str, persona_name: &str, unit_index: usize) -> Self

Create a new context with unit-level variables pre-set.

pub fn set(&mut self, key: &str, value: &str)

Set a variable.

pub fn get(&self, key: &str) -> Option<&str>

Get a variable value.

pub fn vars(&self) -> &HashMap<String, String>

v1.32.0 (D3) — the full variable map, for resolving ${name} placeholders in a store where: clause against the flow context (the Request Binding Contract on the synchronous filter path).

pub fn set_step(&mut self, step_name: &str, step_type: &str, step_index: usize)

Set the current step context variables.

pub fn set_result(&mut self, step_name: &str, result: &str)

Record the result of a step (updates $result and ${StepName}).

pub fn interpolate(&self, text: &str) -> String

Interpolate variables in a string.

Replaces ${name} and $name with their values from the context. Unknown variables are left as-is. Delegates to the free interpolate_vars so the streaming dispatcher interpolates persist field values with byte-identical semantics (D5).

pub fn resolve_named_arg(&self, value: &str, value_kind: &str) -> String

v2.10.0 — resolve a use Tool(k = v) keyword-arg value by its value_kind (reference → binding lookup; literal → interpolation). Delegates to the free resolve_named_arg_value so the sync runner and the streaming dispatcher resolve kwargs byte-identically (D5).

pub fn var_count(&self) -> usize

Number of variables currently set.

pub fn user_bindings(&self) -> Vec<(String, String)>

The user-meaningful bindings — every variable that is not a runner built-in ([BUILTIN_VARS]): let bindings and step results keyed by step name. These are the columns a persist / mutate into a postgresql-backed axonstore writes as a row (v1.30.0). Sorted by name for deterministic SQL.

Trait Implementations
