Enum CodegenError 

pub enum CodegenError {
    Verifier(VerifierErrors),
    ImplLimitExceeded,
    CodeTooLarge,
}

A compilation error.

When Cranelift fails to compile a function, it will return one of these error codes.

Variants

Verifier(VerifierErrors)

A list of IR verifier errors.

This always represents a bug, either in the code that generated IR for Cranelift, or a bug in Cranelift itself.

ImplLimitExceeded

An implementation limit was exceeded.

Cranelift can compile very large and complicated functions, but the implementation has limits that cause compilation to fail when they are exceeded.

CodeTooLarge

The code size for the function is too large.

Different target ISAs may impose a limit on the size of a compiled function. If that limit is exceeded, compilation fails.

Trait Implementations

impl Debug for CodegenError

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

Formats the value using the given formatter.

impl Display for CodegenError

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

Formats the value using the given formatter.

impl Eq for CodegenError

impl Error for CodegenError

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 From<VerifierErrors> for CodegenError

fn from(source: VerifierErrors) -> Self

Converts to this type from the input type.

impl PartialEq for CodegenError

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

Equality operator ==.

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

Inequality operator !=.
