Enum watchexec::fs::Watcher

#[non_exhaustive]
pub enum Watcher {
    Native,
    Poll(Duration),
}

What kind of filesystem watcher to use.

For now only native and poll watchers are supported. In the future there may be additional watchers available on some platforms.

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.

Native

The Notify-recommended watcher on the platform.

For platforms Notify supports, that’s a native implementation, for others it’s polling with a default interval.

Poll(Duration)

Notify’s poll watcher with a custom interval.

Trait Implementations

impl Clone for Watcher

fn clone(&self) -> Watcher

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Watcher

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

Formats the value using the given formatter.

impl Default for Watcher

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Watcher

fn eq(&self, other: &Watcher) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
