#[repr(u8)]
pub enum RootModuleError {
    Returned(RBoxError_),
    Unwound,
}

The errors that a #[export_root_module] function can return.

Variants

Returned(RBoxError_)

When the root loader function returned an error normally

Unwound

When the root loader function panicked

Implementations

impl RootModuleError

pub fn reallocate(&mut self)

Reallocates the error using the current global allocator, to ensure that there is no pointer into the dynamic library.

pub fn into_library_error<M>(self) -> LibraryError

where M: RootModule,

Converts this RootModuleError into a LibraryError, with metadata about the module that failed to load.

Trait Implementations

impl Debug for RootModuleError

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

Formats the value using the given formatter.

impl Display for RootModuleError

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

Formats the value using the given formatter.

impl Error for RootModuleError

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.
