Enum WasmError 

pub enum WasmError {
    Compile(String),
    Instantiation(String),
    Call(String),
    MemoryAccess,
    FuelExhausted,
    Trap(String),
}

Errors that can occur during WASM module compilation, instantiation, or execution.

Variants

Compile(String)

The WASM bytes failed to compile (parse, validate, or codegen error).

Instantiation(String)

The module could not be instantiated (e.g., missing import, link error).

Call(String)

A host function call failed at runtime.

MemoryAccess

Reading from or writing to WASM linear memory failed (bounds check).

FuelExhausted

The WASM module consumed all available fuel and was stopped.

Trap(String)

The WASM module trapped (unreachable, integer divide-by-zero, etc.).

Trait Implementations

impl Clone for WasmError

fn clone(&self) -> WasmError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, f: &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 PartialEq for WasmError

fn eq(&self, other: &WasmError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
