Implementations§

source§

impl AssetSourceBuilder

source

pub fn build( &mut self, id: AssetSourceId<'static>, watch: bool, watch_processed: bool ) -> Option<AssetSource>

Builds a new AssetSource with the given id. If watch is true, the unprocessed source will watch for changes. If watch_processed is true, the processed source will watch for changes.

source

pub fn with_reader( self, reader: impl FnMut() -> Box<dyn AssetReader> + Send + Sync + 'static ) -> Self

Will use the given reader function to construct unprocessed AssetReader instances.

source

pub fn with_writer( self, writer: impl FnMut(bool) -> Option<Box<dyn AssetWriter>> + Send + Sync + 'static ) -> Self

Will use the given writer function to construct unprocessed AssetWriter instances.

source

pub fn with_watcher( self, watcher: impl FnMut(Sender<AssetSourceEvent>) -> Option<Box<dyn AssetWatcher>> + Send + Sync + 'static ) -> Self

Will use the given watcher function to construct unprocessed AssetWatcher instances.

source

pub fn with_processed_reader( self, reader: impl FnMut() -> Box<dyn AssetReader> + Send + Sync + 'static ) -> Self

Will use the given reader function to construct processed AssetReader instances.

source

pub fn with_processed_writer( self, writer: impl FnMut(bool) -> Option<Box<dyn AssetWriter>> + Send + Sync + 'static ) -> Self

Will use the given writer function to construct processed AssetWriter instances.

source

pub fn with_processed_watcher( self, watcher: impl FnMut(Sender<AssetSourceEvent>) -> Option<Box<dyn AssetWatcher>> + Send + Sync + 'static ) -> Self

Will use the given watcher function to construct processed AssetWatcher instances.

source

pub fn with_watch_warning(self, warning: &'static str) -> Self

Enables a warning for the unprocessed source watcher, which will print when watching is enabled and the unprocessed source doesn’t have a watcher.

source

pub fn with_processed_watch_warning(self, warning: &'static str) -> Self

Enables a warning for the processed source watcher, which will print when watching is enabled and the processed source doesn’t have a watcher.

source

pub fn platform_default(path: &str, processed_path: Option<&str>) -> Self

Returns a builder containing the “platform default source” for the given path and processed_path. For most platforms, this will use FileAssetReader / FileAssetWriter, but some platforms (such as Android) have their own default readers / writers / watchers.
