Errors when lowering a Cranelift signature.

Variants

UnsupportedType

A parameter or return type has no LoweredType equivalent.

Fields

position: String

"param N" or "return N", with N the 0-based index.

ty: String

The offending Cranelift type, formatted via its Display impl.

UnsupportedArgumentPurpose

A parameter or return slot has an ArgumentPurpose other than Normal (e.g. struct-return pointer, VM context). These ABI fixups have no equivalent in the wave-1 LoweredOp IR.

Fields

position: String

"param N" or "return N".

purpose: String

Cranelift purpose, formatted via its Display impl.

UnsupportedCallConv

The calling convention requires a host-only fixup that PTX cannot honor.

Fields

conv: String

The Cranelift call conv display.

Trait Implementations

impl Clone for SignatureLoweringError

fn clone(&self) -> SignatureLoweringError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureLoweringError

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

Formats the value using the given formatter.

impl Display for SignatureLoweringError

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

Formats the value using the given formatter.

impl Eq for SignatureLoweringError

impl Error for SignatureLoweringError

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 SignatureLoweringError

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