Struct Error

pub struct Error {
    pub kind: ErrorKind,
    pub paths: Vec<PathBuf>,
}

Notify error type.

Errors are emitted either at creation time of a Watcher, or during the event stream. They range from kernel errors to filesystem errors to argument errors.

Errors can be general, or they can be about specific paths or subtrees. In that later case, the error’s paths field will be populated.

Fields

kind: ErrorKind

Kind of the error.

paths: Vec<PathBuf>

Relevant paths to the error, if any.

Implementations

impl Error

pub fn add_path(self, path: PathBuf) -> Error

Adds a path to the error.

pub fn set_paths(self, paths: Vec<PathBuf>) -> Error

Replaces the paths for the error.

pub fn new(kind: ErrorKind) -> Error

Creates a new Error with empty paths given its kind.

pub fn generic(msg: &str) -> Error

Creates a new generic Error from a message.

pub fn io(err: Error) -> Error

Creates a new i/o Error from a stdlib io::Error.

pub fn io_watch(err: Error) -> Error

Similar to Error::io, but specifically handles io::ErrorKind::NotFound.

pub fn path_not_found() -> Error

Creates a new “path not found” error.

pub fn watch_not_found() -> Error

Creates a new “watch not found” error.

pub fn invalid_config(config: &Config) -> Error

Creates a new “invalid config” error from the given Config.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

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 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.
