Enum cranelift_codegen::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 Display for CodegenError

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

Formats the value using the given formatter.

impl Debug for CodegenError

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

Formats the value using the given formatter.

impl PartialEq<CodegenError> for CodegenError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Eq for CodegenError

impl From<VerifierErrors> for CodegenError

fn from(e: VerifierErrors) -> Self

Performs the conversion.

impl Fail for CodegenError

fn name(&self) -> Option<&str>

Returns the "name" of the error.

fn cause(&self) -> Option<&dyn Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.
