Struct DynamicSourcePolicy 

pub struct DynamicSourcePolicy { /* private fields */ }

Reusable policy for dynamic source evaluated through a named codec.

The policy fixes only the source provenance and codec. Authority and the expected result shape remain explicit inputs to every evaluation, so a guest-language wrapper cannot accidentally retain or widen either one. Callers that need origin detail must provide it in RequestOrigin when constructing the policy.

Implementations

impl DynamicSourcePolicy

pub fn new(codec: Symbol, origin: RequestOrigin) -> Self

Builds a policy with its own decision ledger.

pub fn with_broker( broker: ReadEvalBroker, codec: Symbol, origin: RequestOrigin, ) -> Self

Builds a policy over an existing broker.

Cloned brokers share their ledger, allowing several origin/codec policies to expose one ordered decision stream.

pub fn evaluate_text( &self, cx: &mut Cx, text: impl Into<String>, authority: SourceAuthority, expected_shape: Arc<dyn Shape>, ) -> Result<Value>

Evaluates text decoded through this policy’s codec.

pub fn evaluate_bytes( &self, cx: &mut Cx, bytes: impl Into<Vec<u8>>, authority: SourceAuthority, expected_shape: Arc<dyn Shape>, ) -> Result<Value>

Evaluates bytes decoded through this policy’s codec.

pub fn evaluate_expr( &self, cx: &mut Cx, expr: Expr, authority: SourceAuthority, expected_shape: Arc<dyn Shape>, ) -> Result<Value>

Evaluates an already-decoded expression through the same admission gate.

pub fn evaluate( &self, cx: &mut Cx, source: ReadEvalSource, authority: SourceAuthority, expected_shape: Arc<dyn Shape>, ) -> Result<Value>

Evaluates any supported source form through the shared broker law.

pub fn decisions(&self, cx: &Cx) -> Result<Vec<ReadEvalDecision>>

Returns decisions recorded in the policy’s default run.

pub fn decisions_for_run( &self, cx: &Cx, run: &Ref, ) -> Result<Vec<ReadEvalDecision>>

Returns decisions recorded for run.

pub fn events_for_run(&self, run: &Ref) -> Result<Vec<Event>>

Returns raw ledger events recorded for run.

Trait Implementations

impl Clone for DynamicSourcePolicy

fn clone(&self) -> DynamicSourcePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.
