Struct HotReloadState 

pub struct HotReloadState { /* private fields */ }

State for tracking file changes.

Implementations

impl HotReloadState

pub fn new() -> Result<Self>

Initializes the file-tracking context.

To register a shader for change-tracking call Shader::watch_sources once with the state returned by this function. To register a file for change-tracking, call HotReloadState::watch_file.

pub fn update_changes(&mut self)

Saves in self the set of watched files that changed since the last time this function was called.

Once this call completes, the Self::file_changed method can be used to check if a particular file (assuming it was added to the watch list with Self::watch_file) has changed since the last time [Self::updated_changes] was called.

pub fn watch_file(&mut self, path: &Path) -> Result<()>

Registers a files for change-tracking.

pub fn file_changed(&self, path: &Path) -> bool

Checks if the specified file change was detected at the time of calling Self::update_changes.
