Type for errors occurring during Wasm runtime construction.

Variants

CodeNotFound

Code could not be read from the state.

ApplySnapshotFailed

Failure to reinitialize runtime instance from snapshot.

ErasingFailed(String)

Failure to erase the wasm memory.

Depending on the implementation might mean failure of allocating memory.

InvalidModule

Wasm code failed validation.

CantDeserializeWasm

Wasm code could not be deserialized.

InvalidHeapPages

The number of heap pages requested is disallowed by the module.

Instantiation(String)

Other(String)

Other error happenend.

Trait Implementations

impl Debug for WasmError

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

Formats the value using the given formatter.

impl Display for WasmError

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

Formats the value using the given formatter.

impl Error for WasmError

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

Returns 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.

impl From<WasmError> for Error

fn from(source: WasmError) -> Self

Converts to this type from the input type.
