Exception

struct WasmVM::Exception::Exception : public std::runtime_error

Exception(std::string msg)

struct WasmVM::Exception::Parse : public Exception

Parse(std::string msg, std::pair<size_t, size_t> location)

std::pair<size_t, size_t> location

struct WasmVM::Exception::Decode : public Exception

Decode(std::string msg, size_t location)

size_t location

struct WasmVM::Exception::unexpected_eof : public Exception

unexpected_eof()

struct WasmVM::Exception::interrupted : public Exception

Thrown by Stack::run() when the embedder’s interrupt flag reads true. Not a wasm-level exception: the guest’s try_table/catch_all cannot swallow it.

interrupted()

struct WasmVM::Exception::Trap : public Exception

Base of every WebAssembly trap escaping Stack::run(): the guest hit a condition the spec defines as trapping (unreachable, integer divide by zero, out-of-bounds memory or table access, indirect call type mismatch, null reference, failed cast, …). The concrete trap types are private to WasmVM; catch this base.

Trap(std::string msg)

struct WasmVM::Exception::Uncaught : public Exception

A wasm throw no try_table in the guest caught, escaping Stack::run(). Not a Trap.

Uncaught(std::shared_ptr<WasmException> exn)

std::shared_ptr<WasmException> exn

The thrown exception: its tag address and payload values.

struct WasmVM::Exception::Warning

Warning(std::string msg)

Warning(const char *msg)

static void regist(std::function<void(std::string)> handler)
