Struct xtask_wasm::Watch

#[non_exhaustive]
pub struct Watch {
    pub watch_paths: Vec<PathBuf>,
    pub exclude_paths: Vec<PathBuf>,
    pub workspace_exclude_paths: Vec<PathBuf>,
    pub debounce: Duration,
}

Watches over your project’s source code, relaunching a given command when changes are detected.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

watch_paths: Vec<PathBuf>

Watch specific file(s) or folder(s).

The default is the workspace root.

exclude_paths: Vec<PathBuf>

Paths that will be excluded.

workspace_exclude_paths: Vec<PathBuf>

Paths, relative to the workspace root, that will be excluded.

debounce: Duration

Throttle events to prevent the command to be re-executed too early right after an execution already occurred.

The default is 2 seconds.

Implementations

impl Watch

pub fn watch_path(self, path: impl AsRef<Path>) -> Watch

Add a path to watch for changes.

pub fn watch_paths( self, paths: impl IntoIterator<Item = impl AsRef<Path>> ) -> Watch

Add multiple paths to watch for changes.

pub fn exclude_path(self, path: impl AsRef<Path>) -> Watch

Add a path that will be ignored if changes are detected.

pub fn exclude_paths( self, paths: impl IntoIterator<Item = impl AsRef<Path>> ) -> Watch

Add multiple paths that will be ignored if changes are detected.

pub fn exclude_workspace_path(self, path: impl AsRef<Path>) -> Watch

Add a path, relative to the workspace, that will be ignored if changes are detected.

pub fn exclude_workspace_paths( self, paths: impl IntoIterator<Item = impl AsRef<Path>> ) -> Watch

Add multiple paths, relative to the workspace, that will be ignored if changes are detected.

pub fn debounce(self, duration: Duration) -> Watch

Set the debounce duration after relaunching the command.

pub fn run(self, commands: impl Into<CommandList>) -> Result<(), Error>

Run the given command, monitor the watched paths and relaunch the command when changes are detected.

Workspace’s target directory and hidden paths are excluded by default.

Trait Implementations

impl Args for Watch

fn clone(&self) -> Watch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CommandFactory for Watch

fn command<'b>() -> Command

Build a [Command] that can instantiate Self.

fn command_for_update<'b>() -> Command
