Struct zng_ext_fs_watcher::WatcherHandle

source ·
pub struct WatcherHandle(/* private fields */);
Expand description

Represents an active file or directory watcher in WATCHER.

Implementations§

source§

impl WatcherHandle

source

pub fn dummy() -> Self

Handle to no watcher.

source

pub fn is_permanent(&self) -> bool

If perm was called in another clone of this handle.

If true the resource will stay in memory for the duration of the app, unless force_drop is also called.

source

pub fn force_drop(self)

Force drops the watcher, meaning it will be dropped even if there are other handles active.

source

pub fn is_dropped(&self) -> bool

If the watcher is dropped.

source

pub fn perm(self)

Drop the handle without dropping the watcher, the watcher will stay active for the duration of the app process.
