Struct notify::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) -> Self

Adds a path to the error.

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

Replaces the paths for the error.

pub fn new(kind: ErrorKind) -> Self

Creates a new Error with empty paths given its kind.

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

Creates a new generic Error from a message.

pub fn io(err: Error) -> Self

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

pub fn path_not_found() -> Self

Creates a new "path not found" error.

pub fn watch_not_found() -> Self

Creates a new "watch not found" error.

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

Creates a new "invalid config" error from the given Config.

impl Error for Error

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

pub fn source(&self) -> Option<&(dyn Error + 'static)>

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

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

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

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

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()
