Struct Step 

pub struct Step {
    pub id: String,
    pub after: Vec<String>,
    pub gate: Option<Guard>,
    pub done: Option<Guard>,
    pub posture: Option<String>,
    pub ground: Option<String>,
    pub allow: Vec<String>,
    pub deny: Vec<String>,
    pub terminal: bool,
}

A node in the flow DAG — the only node type.

Fields

id: String

Unique step id.

after: Vec<String>

Dependency step ids; this step is only eligible once all are done.

gate: Option<Guard>

Extra eligibility predicate beyond dependencies.

done: Option<Guard>

Completion condition. Required for non-terminal steps.

posture: Option<String>

Instruction imposed while this step is active (projected as steering).

ground: Option<String>

A grounding template projected while active: a curated, State-interpolated fact line that pins the model to known values (anti-hallucination). See render_ground. Serializable, like posture.

allow: Vec<String>

Tools available while this step is active (whitelist; empty = no restriction).

deny: Vec<String>

Tools forbidden while this step is active.

terminal: bool

A terminal step — reaching it (deps + gate) marks it done with no milestone.

Trait Implementations

impl Clone for Step

fn clone(&self) -> Step

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Step

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Step

fn deserialize<__D>( __deserializer: __D, ) -> Result<Step, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Step

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
