Expand description

An error that can occur when loading or reloading a model

Variants

Compile

Model failed to compile

Io(Error)

I/O error while loading the model

LibLoading(Error)

Failed to load the model’s dynamic library

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().

Notify(Error)

Error while watching the model code for changes

CargoMetadata(Error)

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

AmbiguousPath

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.

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).
