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

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).

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)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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 self, req: &mut Demand<'a>)

🔬 This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
