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

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

Fields

message: &'static str

Tell where the allocation came from

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.
