Errors that can occur when using a Wasm runtime.

Variants

AllocationTooLarge

Attempt to allocate a buffer larger than i32::MAX.

InvalidAlignment

Attempt to allocate a buffer that’s aligned to an invalid boundary.

AllocationFailed

Call to cabi_realloc returned a negative value instead of a valid address.

DeallocateInvalidAddress

Attempt to deallocate an address that’s after i32::MAX.

FunctionNotFound(String)

Attempt to load a function not exported from a module.

NotAFunction(String)

Attempt to load a function with a name that’s used for a different import in the module.

MissingMemory

Attempt to load the memory export from a module that doesn’t export it.

NotMemory

Attempt to load the memory export from a module that exports it as something else.

InvalidString(FromUtf8Error)

Attempt to load a string from a sequence of bytes that doesn’t contain a UTF-8 string.

InvalidNumber(TryFromIntError)

Attempt to create a GuestPointer from an invalid address representation.

InvalidVariant

Attempt to load an enum type but the discriminant doesn’t match any of the variants.

Fields

type_name: &'static str

The enum type that failed being loaded.

discriminant: i64

The invalid discriminant that was received.

Custom(Error)

A custom error reported by one of the Wasm host’s function handlers.

Wasmer(RuntimeError)

Wasmer runtime error.

WasmerMemory(MemoryAccessError)

Attempt to access an invalid memory address using Wasmer.

Wasmtime(Error)

Wasmtime error.

WasmtimeTrap(Trap)

Wasmtime trap during execution.

Trait Implementations

impl Debug for RuntimeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for RuntimeError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for RuntimeError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
