A deterministic, typed lowering failure.

Variants

UnsupportedPointerWidth

The target is not 64-bit.

Fields

bits: u8

The offending pointer width in bits.

TooManyFunctions

The module has more functions than a u32 can index.

Fields

count: usize

The offending function count.

RegisterFileTooLarge

A function’s register file cannot be addressed with 32-bit slot offsets.

Fields

function: FunctionId

The offending function.

register_count: u32

Its register count.

EntrySignatureMismatch

A lowered function’s entry signature differs from the native ABI.

Fields

function: FunctionId

The offending function.

IrVerification

Cranelift’s IR verifier rejected a lowered function.

Fields

function: FunctionId

The offending function.

message: String

The verifier’s diagnostics.

Trait Implementations

impl Clone for LowerError

fn clone(&self) -> LowerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LowerError

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

Formats the value using the given formatter.

impl Display for LowerError

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

Formats the value using the given formatter.

impl Eq for LowerError

impl Error for LowerError

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 LowerError

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

Equality operator ==.

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

Inequality operator !=.
