Struct CallFrame 

pub struct CallFrame {
    pub flow_id: FlowId,
    pub ir_hash: Hash,
    pub call_step_id: Option<StepId>,
    pub inputs_snapshot: Value,
    pub vars: BTreeMap<String, Value>,
    pub iter_stack: Vec<IterState>,
    pub next_index: u64,
}

One frame of the live call stack (07 §3.2 refinement; frames[0] is the root flow frame). Pending spine incorporation of the refined fields.

Fields

flow_id: FlowId

The flow executing in this frame.

ir_hash: Hash

Content hash of that flow’s IR.

call_step_id: Option<StepId>

The host call step’s id; absent for the root frame and for handler-repair launched frames (spine §9).

inputs_snapshot: Value

Call-by-value input snapshot taken when the frame was pushed; never updated from a newer IR (07 §5.2).

vars: BTreeMap<String, Value>

let bindings materialized in this frame (SSA, single assignment).

iter_stack: Vec<IterState>

Live foreach iterations, innermost last.

next_index: u64

Index of the next body step to schedule in this frame.

Trait Implementations

impl Clone for CallFrame

fn clone(&self) -> CallFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallFrame

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CallFrame

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for CallFrame

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for CallFrame

fn eq(&self, other: &CallFrame) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for CallFrame

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
