All the possible errors that could happen when loading a library, or a module.

Variants

OpenError

When a library can’t be loaded, because it doesn’t exist.

Fields

path: PathBuf

The path to the library

err: Box<Error>

The cause of the error

GetSymbolError

When a function/static does not exist.

Fields

library: PathBuf

The path to the library

symbol: Vec<u8>

The name of the function/static.Does not have to be utf-8.

err: Box<Error>

The cause of the error

ParseVersionError(ParseVersionError)

The version string could not be parsed into a version number.

IncompatibleVersionNumber

The version numbers of the library was incompatible.

Fields

library_name: &'static str

expected_version: VersionNumber

actual_version: VersionNumber

RootModule

Error returned by the root module

Fields

err: RootModuleError

The error returned by the #[export_root_module] function.

module_name: &'static str

version: VersionStrings

AbiInstability(RBoxError)

The abi is incompatible. The error is opaque,since the error always comes from the main binary (dynamic libraries can be loaded from other dynamic libraries).

InvalidAbiHeader(AbiHeader)

The type used to check that this is a compatible abi_stable is not the same.

InvalidCAbi

When Rust changes how it implements the C abi,

Fields

expected: RBoxError

found: RBoxError

Many(RVec<Self>)

There could have been 0 or more errors in the function.

Trait Implementations

impl Debug for LibraryError

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

Formats the value using the given formatter.

impl Display for LibraryError

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

Formats the value using the given formatter.

impl Error for LibraryError

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<ParseVersionError> for LibraryError

fn from(v: ParseVersionError) -> LibraryError

Converts to this type from the input type.
