An error that may occur upon instantiation of a Wasm module.

Variants

ImportsExternalsLenMismatch

Caused when the number of required imports does not match the number of given externals upon module instantiation.

ImportsExternalsMismatch

Fields

expected: ExternType

The expected external value for the module import.

actual: Extern

The actually found external value for the module import.

Caused when a given external value does not match the type of the required import for module instantiation.

SignatureMismatch

Fields

expected: FuncType

The expected function signature for the function import.

actual: FuncType

The actual function signature for the function import.

Caused when a function has a mismatching signature.

Table(TableError)

Occurs when an imported table does not satisfy the required table type.

Memory(MemoryError)

Occurs when an imported memory does not satisfy the required memory type.

Global(GlobalError)

Occurs when an imported global variable does not satisfy the required global type.

ElementSegmentDoesNotFit

Fields

table: Table

The table of the element segment.

offset: u32

The offset to store the amount of elements into the table.

amount: u32

The amount of elements with which the table is initialized at the offset.

Caused when an element segment does not fit into the specified table instance.

FoundStartFn

Fields

index: u32

The index of the found start function.

Caused when the start function was unexpectedly found in the instantiated module.

Trait Implementations

impl Debug for InstantiationError

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

Formats the value using the given formatter.

impl Display for InstantiationError

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

Formats the value using the given formatter.

impl Error for InstantiationError

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.
