Native watcher failures that are not recoverable through a baseline rescan.

Variants

InvalidOptions

Queue or volume bounds are invalid.

RootIsNotDirectory

Watch root is not a directory.

SymbolicLinkDirectory

A demanded directory traverses a symbolic link and cannot be mapped back to one exact namespace path.

ObservedPathNotDirectory

A demanded observer path is not a directory.

UnrepresentablePath

A demanded namespace path cannot be represented exactly on this host.

RootChanged

A separately opened capture root does not match the watched directory.

Io(String)

Root path I/O failed.

Backend(String)

Native backend setup failed.

StatePoisoned

Watcher state synchronization was poisoned.

RescanAlreadyInProgress

A baseline scan is already active.

NoRescanInProgress

No baseline scan is active.

RescanInProgress

Polling while a baseline is being built is ambiguous.

ZeroPollLimit

Poll output must have a positive bound.

SequenceExhausted

Process-local cursor arithmetic overflowed.

AllocationFailed

Bounded output allocation failed.

Cancelled(CancellationError)

Polling was cooperatively cancelled.

Work(WorkError)

Exact work overflowed or exceeded the admitted budget.

Trait Implementations

impl Debug for NativeWatchError

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

Formats the value using the given formatter.

impl Display for NativeWatchError

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

Formats the value using the given formatter.

impl Error for NativeWatchError

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.
