Module runtime 

Minimal register-IR execution core.

This is the first Phase 2 runtime slice: execute straight-line lowered IR independently from validation. Broader control flow, calls, memory, tables, traps, and host integration are added in later checkpoints.

Re-exports

pub use host::HostFunction;

pub use host::link_func;

Modules

gpu

Optional GPU backend slot for bulk SIMD offload.

host

Host functions: native callables registered with a Store that WASM modules can import and call.

verify

Numerical correctness verification for GPU offload kernels (Layer 2).

Structs

Imports

Entities provided by the host to satisfy a module’s state imports (memories, globals, tables), resolved eagerly at instantiation. Function imports resolve separately and lazily via Store::register_host_func.

RuntimeError

Runtime execution error.

Store

Mutable state of an instantiated module.

Table

A WebAssembly table instance.

Enums

RuntimeErrorKind

Specific runtime execution failures.

RuntimeTrap

WebAssembly runtime traps surfaced by the interpreter.

Value

A runtime WebAssembly value.

Constants

PAGE_SIZE

Size of one WebAssembly memory page in bytes.

Functions

execute_export

Execute an exported lowered function by name.

execute_func

Execute a single lowered function with positional arguments.

Type Aliases

LinkGroup

A link group: instances that can reach each other’s funcref values by instance id. Created per link cluster (e.g. one per spec test file).
