Enum WasmLowerError 

pub enum WasmLowerError {
    Unsupported(&'static str),
}

Why the AOT WebAssembly backend declined to lower a program. The backend is total on its supported fragment and rejects everything else explicitly (never miscompiles): the corpus ratchet asserts each program is either lowered-and-correct or on the allowed-unsupported list, so a program silently leaving the fragment fails a test rather than emitting wrong code.

Variants

Unsupported(&'static str)

An op, type, or shape outside the current phase’s supported fragment (the &str names what is not yet handled, e.g. "collection op", "non-scalar parameter").

Trait Implementations

impl Clone for WasmLowerError

fn clone(&self) -> WasmLowerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmLowerError

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

Formats the value using the given formatter.

impl Display for WasmLowerError

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

Formats the value using the given formatter.

impl Error for WasmLowerError

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 WasmLowerError

fn eq(&self, other: &WasmLowerError) -> 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.
