Enum FileWatcherBuildError 

#[non_exhaustive]
pub enum FileWatcherBuildError {
    CurrentDirectory(Arc<Error>),
    Notify(Arc<Error>),
}

An error coming from a FileWatcherBuilder.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CurrentDirectory(Arc<Error>)

Invalid current working directory.

This error can happen if the current directory does not exist, or if we don’t have the necessary permissions to access it.

Notify(Arc<Error>)

Encountered a problem while creating a Watcher.

Trait Implementations

impl Clone for FileWatcherBuildError

fn clone(&self) -> FileWatcherBuildError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FileWatcherBuildError

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

Formats the value using the given formatter.

impl Display for FileWatcherBuildError

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

Formats the value using the given formatter.

impl Error for FileWatcherBuildError

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.

impl From<Arc<Error>> for FileWatcherBuildError

fn from(source: Arc<Error>) -> Self

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
