Enum cretonne_codegen::result::CtonError

pub enum CtonError {
    InvalidInput,
    Verifier(Error),
    ImplLimitExceeded,
    CodeTooLarge,
}

A compilation error.

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

Variants

InvalidInput

The input is invalid.

This error code is used by a WebAssembly translator when it encounters invalid WebAssembly code. This should never happen for validated WebAssembly code.

Verifier(Error)

An IR verifier error.

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

ImplLimitExceeded

An implementation limit was exceeded.

Cretonne 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 Fail for CtonError

fn cause(&self) -> Option<&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.

Important traits for Causes<'f>

impl<'f> Iterator for Causes<'f> type Item = &'f (Fail + 'static);

fn causes(&self) -> Causes

Returns a iterator over the causes of this Fail with itself as the first item and the root_cause as the final item.

fn root_cause(&self) -> &(Fail + 'static)

Returns the "root cause" of this Fail - the last value in the cause chain which does not return an underlying cause.

impl Display for CtonError

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

Formats the value using the given formatter.

impl Debug for CtonError

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for CtonError

fn eq(&self, __arg_0: &CtonError) -> bool

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

fn ne(&self, __arg_0: &CtonError) -> bool

This method tests for !=.

impl Eq for CtonError

impl From<Error> for CtonError

fn from(e: Error) -> Self

Performs the conversion.
