Expand description

A content-addressed program: a set of FunctionBlobs plus program-level metadata.

This is the storage / cache representation. Before execution the linker flattens it into a LinkedProgram.

Fields§

§entry: FunctionHash

Hash of the entry-point function.

§function_store: HashMap<FunctionHash, FunctionBlob>

All function blobs keyed by content hash.

§top_level_locals_count: u16

Number of locals used by top-level code.

§top_level_local_storage_hints: Vec<StorageHint>

Storage hints for top-level locals.

§module_binding_names: Vec<String>

Module-binding variable names (index -> name).

§module_binding_storage_hints: Vec<StorageHint>

Storage hints for module bindings.

§function_local_storage_hints: Vec<Vec<StorageHint>>

Per-function local storage hints.

§top_level_frame: Option<FrameDescriptor>

Typed frame layout for top-level locals.

§top_level_local_concrete_types: Vec<ConcreteType>

Per-slot fully-resolved ConcreteType for top-level locals.

ADR-006 §2.7.5 conduit (content-addressed mirror of BytecodeProgram.top_level_local_concrete_types). Survives the Program → link() → LinkedProgram → BytecodeProgram round-trip so JIT compilation of in-memory-compiled programs can use the typed-array / TypedObject fast paths. Not serialised — ConcreteType carries opaque registry IDs that aren’t a stable wire shape; cached-program loads fall through to the legacy NaN-boxed path.

§function_local_concrete_types: Vec<Vec<ConcreteType>>

Per-user-function per-MIR-slot ConcreteType side-table.

ADR-006 §2.7.5 conduit (W12-jit-aggregate-non-array, 2026-05-12): content-addressed mirror of BytecodeProgram.function_local_concrete_types. Survives the Program → link() → LinkedProgram → BytecodeProgram round- trip so JIT compilation of in-memory-compiled programs can use the TypedObject Aggregate short-circuit inside user-function bodies (Smoke 1.5 divide, Smoke 2 first_positive, 28 stdlib helpers). Not serialised — same rationale as top_level_local_concrete_types.

§function_return_concrete_types: Vec<ConcreteType>

Per-user-function declared ConcreteType for the return value.

ADR-006 §2.7.5 conduit (W12-jit-call-return-kind close, 2026-05-12): content-addressed mirror of BytecodeProgram.function_return_concrete_types. Survives the Program → link() → LinkedProgram → BytecodeProgram round-trip so the conduit can stamp Call-terminator destination slots from the callee’s declared return type. Not serialised — same rationale as the sibling *_concrete_types side-tables.

§monomorphized_method_call_sites: HashMap<(Span, Option<usize>), usize>

ADR-006 §2.7.5 conduit (V3-S6b-jit-method-monomorph-conduit close, 2026-05-15): content-addressed mirror of BytecodeProgram.monomorphized_method_call_sites. Survives the Program → link() → LinkedProgram → BytecodeProgram round-trip so the conduit producer can lift function_return_concrete_types[specialized_idx] into the destination slot’s ConcreteType at MirConstant::Method Call- terminator sites. Not serialised — opaque per-program FunctionId indices aren’t a stable wire shape.

§value_call_return_concrete_types: HashMap<(Span, Option<usize>), ConcreteType>

ADR-006 §2.7.5 conduit (cluster-2-cw-IB-class-b close, 2026-05-16): content-addressed mirror of BytecodeProgram.value_call_return_concrete_types. Survives the Program → link() → LinkedProgram → BytecodeProgram round-trip so the conduit producer can stamp value-call TerminatorKind::Call destination slots from the closure-bound callee’s inferred return ConcreteType. Not serialised — ConcreteType carries opaque registry IDs that aren’t a stable wire shape.

§operator_trait_dispatch_sites: HashMap<Span, (String, u16)>

ADR-006 §2.7.5 conduit (W10 jit-call-method-user-trait-fix close, 2026-05-17): content-addressed mirror of BytecodeProgram.operator_trait_dispatch_sites. Survives the Program → link() → LinkedProgram → BytecodeProgram round-trip so the JIT consumer can re-emit user-type binary/unary trait-dispatch as method-call IR. Not serialised — Spans carry source-position offsets that aren’t a stable wire shape.

§data_schema: Option<DataFrameSchema>

DataFrame schema for column name resolution.

§type_schema_registry: TypeSchemaRegistry

Type schema registry for TypedObject field resolution.

§trait_method_symbols: HashMap<String, String>

Trait method dispatch registry.

§foreign_functions: Vec<ForeignFunctionEntry>

Foreign function metadata table.

§native_struct_layouts: Vec<NativeStructLayoutEntry>

Native type C layout metadata table.

§debug_info: DebugInfo

Debug information (source files, variable names).

§closure_function_layouts_by_name: HashMap<String, Arc<ClosureLayout>>

Closure spec §14.6 (H6.5): per-function-name ClosureLayout side-table threaded through the content-addressed Program so it survives the link() → LinkedProgram → BytecodeProgram round- trip. Keyed by function name because the content-addressed store reorders blobs topologically; the linker remaps to post-link function-id positions in LinkedProgram.closure_function_layouts. Not serialised — programs loaded from disk fall back to the legacy HeapValue::Closure variant.

§trait_vtables: HashMap<String, Arc<VTable>>

ADR-006 §2.7.24 Q25.C trait-object vtable registry. Keyed by "Trait::ConcreteType" strings (matching the existing trait_method_symbols key prefix). Built at impl-block compilation; consumed at op_box_trait_object runtime to build Arc<TraitObjectStorage>. Not serialised because Arc<VTable> is not a stable wire shape; in cached-program-load mode the vtables are rebuilt at link time from trait_method_symbols.

§has_imported_const_inline: bool

R8 W8 Cluster A surface-and-stop flag (2026-05-25). Mirror of BytecodeProgram::has_imported_const_inline for the content- addressed Program shape; propagated through the linker so the JIT executor can deopt the whole program to the bytecode interpreter when imported pub const identifiers were inlined-at-use by compile_expr_identifier. v0.4 root-cause fix per close-summary §5.16. NOT serialised — compile-time state.

§has_w17_marshal_residual: bool

R8 W9 B1 W17-marshal-return surface-and-stop flag (2026-05-25). Mirror of BytecodeProgram::has_w17_marshal_residual for the content-addressed Program shape; propagated through the linker so the JIT executor can deopt the whole program to the bytecode interpreter when the program contains direct calls to imported stdlib functions (which route through Ptr(HeapKind::ModuleFn) callees that the JIT’s jit_call_value silently returns TAG_NULL for). v0.4 root-cause fix per close-summary §5.16. NOT serialised — compile-time state.
