Struct DecisionEngine 

pub struct DecisionEngine { /* private fields */ }

Sequential policy engine that short-circuits on deny or defer.

Implementations

impl DecisionEngine

pub fn new() -> Self

Creates an empty decision engine that allows by default.

pub fn register_node<N: DecisionNode + 'static>( &mut self, node: N, ) -> RuntimeResult<()>

Appends one uniquely named node within the count and name-byte limits. Rejection leaves evaluation order and existing nodes unchanged.

pub fn len(&self) -> usize

Returns the number of decision nodes.

pub fn is_empty(&self) -> bool

Reports whether no decision nodes are configured.

pub fn node_names(&self) -> &[String]

Returns decision node names in evaluation order.

pub fn evaluate( &self, command: &CommandEnvelope, context: &dyn RuntimeContext, ) -> RuntimeResult<DecisionOutcome>

Evaluates nodes in order and returns the first non-allow outcome.

Trait Implementations

impl Debug for DecisionEngine

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

Formats the value using the given formatter.

impl Default for DecisionEngine

fn default() -> DecisionEngine

Returns the “default value” for a type.
