Error messages for all Module methods

Variants

Undeclared(String)

Indicates an identifier was used before it was declared

IncompatibleDeclaration(String)

Indicates an identifier was used as data/function first, but then used as the other

IncompatibleSignature(String, Signature, Signature)

Indicates a function identifier was declared with a different signature than declared previously

IncompatibleDataTls(String, bool, bool)

Indicates a data object was declared as TLS but previously declared as not TLS or vice versa.

DuplicateDefinition(String)

Indicates an identifier was defined more than once

InvalidImportDefinition(String)

Indicates an identifier was defined, but was declared as an import

Compilation(CodegenError)

Wraps a cranelift-codegen error

Allocation

Memory allocation failure from a backend

Only the std builds carry this variant: the payload is a std::io::Error and the only producer is cranelift-jit, which needs std anyway.

Fields

err: Error

Io error the allocation failed with

Backend(Error)

Wraps a generic error from a backend

Flag(SetError)

Wraps an error from a flag definition.

Trait Implementations

impl Debug for ModuleError

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

Formats the value using the given formatter.

impl Display for ModuleError

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

Formats the value using the given formatter.

impl Error for ModuleError

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<CodegenError> for ModuleError

fn from(source: CodegenError) -> Self

Converts to this type from the input type.

impl<'a> From<CompileError<'a>> for ModuleError

fn from(err: CompileError<'a>) -> Self

Converts to this type from the input type.

impl From<SetError> for ModuleError

fn from(source: SetError) -> Self

Converts to this type from the input type.
