Struct FunctionPlan 

pub struct FunctionPlan { /* private fields */ }

Immutable declaration metadata shared by guest function implementations.

Equality is plan identity: two independently built plans compare equal when their stable display symbol and complete declarations are equal.

Implementations

impl FunctionPlan

pub fn new( display_identity: Symbol, parameters: Vec<ParameterDescriptor>, captures: Vec<CaptureDescriptor>, result_shape: Option<ShapeId>, ) -> Result<Self, PlanError>

Validates and freezes one declaration.

pub fn display_identity(&self) -> &Symbol

Returns the stable human-facing identity of this declaration.

pub fn parameters(&self) -> &[ParameterDescriptor]

Returns parameter descriptors in declaration order.

pub fn captures(&self) -> &[CaptureDescriptor]

Returns capture slots in stable declaration order.

pub const fn result_shape(&self) -> Option<ShapeId>

Returns the declared result Shape identifier.

pub fn browse(&self) -> BrowseProjection

Builds the canonical browse projection without resolving or executing a Shape.
