Crate sim_lib_function 

Language-neutral immutable function plans.

A FunctionPlan records declaration metadata only. It deliberately has no evaluation or invocation surface; later instance machinery composes a plan with a concrete guest policy.

A body remains a statically selected guest policy. Type erasure cannot meet the bound of the future instance type:

use std::any::Any;

trait GuestBodyPolicy {}
struct FunctionInstance<B: GuestBodyPolicy>(B);

fn erase(body: Box<dyn Any>) -> FunctionInstance<Box<dyn Any>> {
    FunctionInstance(body)
}

Structs

BoundArgument

An input paired with its exact origin.

BoundCall

A stable, lossless call record awaiting guest-policy decisions.

BrowseProjection

Canonical, inert projection of a function’s browsable Shape metadata.

CallInput

Mutable call input assembled by kernel and guest adapters.

CallMode

The ways in which a caller may address a parameter.

CaptureDescriptor

Stable metadata for one lexical capture slot.

CapturedBinding

One shared binding cell paired with its identity in the managed graph.

FunctionInstance

A language-neutral, managed function object with a concrete guest body.

FunctionPlan

Immutable declaration metadata shared by guest function implementations.

ParameterDescriptor

Stable declaration metadata for one parameter.

PlanError

A construction failure for an immutable function plan.

Enums

ArgumentInput

One undecided input supplied to the neutral adaptation boundary.

ArgumentOrigin

The exact place at which an argument entered the call boundary.

InstanceError

Failure to construct a managed function instance.

ParameterKind

The declaration role of a parameter.

Traits

FunctionBodyPolicy

Guest-owned execution policy for one concrete function body type.

Functions

bind

Freezes an assembled input stream without applying a language rule.

dispatch_method_body

Projects a function instance into a dispatch method body.

validate_capture_bindings

Validates that concrete capture cells exactly match every frozen plan slot.
