An error that can occur when loading or reloading a model

Variants

LoadingLibrary(Error)

Error loading model library

LoadingVersion(Error)

Error loading Fornjot version that the model uses

LoadingInit(Error)

Error loading the model’s init function

VersionMismatch

Host version and model version do not match

Fields

host: String

The host version

model: String

The model version

Compile

Model failed to compile

Fields

output: String

The compiler output

Io(Error)

I/O error while loading the model

InitializeModel(Error)

Initializing a model failed.

NoModelRegistered

The user forgot to register a model when calling fj::register_model!().

Shape(Error)

An error was returned from fj::models::Model::shape().

ShapeProcessor(Error)

An error was returned from fj_operations::shape_processor::ShapeProcessor::process().

Notify(Error)

Error while watching the model code for changes

CargoMetadata(Error)

An error occurred while trying to use evaluate cargo_metadata::MetadataCommand.

AmbiguousPath

The user pointed us to a directory, but it doesn’t look like that was a crate root (i.e. the folder containing Cargo.toml).

Fields

dir: PathBuf

The model directory supplied by the user.

possible_paths: Vec<PathBuf>

The directories for each crate in the workspace, relative to the workspace root.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
