Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InitialTableSizeExceeded

Initial table size outside allowed bounds.

Fields

max: u32

Allowed maximum table size.

actual: u32

Actual initial table size specified in the Wasm.

MaxTableSizeExceeded

Maximum table size outside allowed bounds.

Fields

max: u32

Allowed maximum table size.

actual: u32

Actual max table size specified in the Wasm.

MoreThanOneTable

Number of the tables in a Wasm must be at most one.

BrTableSizeExceeded

Length of a br_table exceeded the maximum allowed size.

Fields

max: u32

Maximum allowed br_table length.

actual: usize

Actual size of a br_table in the code.

TooManyGlobals

Declared number of globals exceeds allowed limit.

Fields

max: u32

Maximum allowed globals.

actual: usize

Actual number of globals declared in the Wasm.

TooManyParameters

Module declares a function type with too many parameters.

Fields

max: u32

Maximum allowed parameters.

actual: usize

Actual number of parameters a function has in the Wasm.

MissingHostFunction

Module tries to import a function that the host does not provide.

IncorrectGlobalOperation

Opcode for a global access refers to a non-existing global

Fields

Trait Implementations

impl Clone for WasmValidationError

fn clone(&self) -> WasmValidationError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WasmValidationError

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

Formats the value using the given formatter.

impl Display for WasmValidationError

impl Error for WasmValidationError

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<WasmValidationError> for PreprocessingError

fn from(source: WasmValidationError) -> Self

Converts to this type from the input type.
