Struct BranchNode 

pub struct BranchNode {
    pub id: String,
    pub name: Option<String>,
    pub on: Option<String>,
    pub agent_hash: Option<String>,
    pub cases: Vec<BranchCase>,
}

A branch node: routes on a typed output.

Fields

id: String

The node’s stable id, unique within the document.

name: Option<String>

Optional short display label for this node. See the module docs’ “The optional node display name” section for the bound and the deliberate hash-inclusion contrast with the agent name field. Additive: absent on the wire when unset.

on: Option<String>

Optional opaque reference to the typed value the branch routes on. Recorded as DATA; not resolved in this crate.

agent_hash: Option<String>

Content hash of the agent that decides a BranchCondition::ModelDecision case, in sha256:<64 lowercase hex> form. Present only on a branch that carries a model-decision case: the engine drives this agent with the routed value and maps its reply to a case name. Additive: absent on the wire when unset, so a purely expression-driven branch (and every document written before this field existed) serializes byte for byte as before. [crate::validate] reports a model-decision case with no agent here as a node-precise error.

cases: Vec<BranchCase>

The cases, each a named condition. An expression condition is evaluated against the routed value; a model-decision condition is resolved by the node’s agent_hash agent. The first matching case in author order wins, and the engine records the choice as a crate::document-external BranchTaken event.

Trait Implementations

impl Clone for BranchNode

fn clone(&self) -> BranchNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BranchNode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BranchNode

impl JsonSchema for BranchNode

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

The name of the generated JSON Schema.

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