Struct bevy::asset::LoadContext
[−]pub struct LoadContext<'a> { /* private fields */ }
Expand description
An asynchronous context where an Asset
is processed.
The load context is created by the AssetServer
to process an asset source after loading its
contents into memory. It is then passed to the appropriate AssetLoader
based on the file
extension of the asset’s path.
An asset source can define one or more assets from a single source path. The main asset is set
using LoadContext::set_default_asset
and sub-assets are defined with
LoadContext::set_labeled_asset
.
Implementations
impl<'a> LoadContext<'a>
impl<'a> LoadContext<'a>
pub fn has_labeled_asset(&self, label: &str) -> bool
pub fn has_labeled_asset(&self, label: &str) -> bool
Returns true
if the load context contains an asset with the specified label.
pub fn set_default_asset<T>(&mut self, asset: LoadedAsset<T>) where
T: Asset,
pub fn set_default_asset<T>(&mut self, asset: LoadedAsset<T>) where
T: Asset,
Sets the primary asset loaded from the asset source.
pub fn set_labeled_asset<T>(
&mut self,
label: &str,
asset: LoadedAsset<T>
) -> Handle<T> where
T: Asset,
pub fn set_labeled_asset<T>(
&mut self,
label: &str,
asset: LoadedAsset<T>
) -> Handle<T> where
T: Asset,
Sets a secondary asset loaded from the asset source.
pub fn get_handle<I, T>(&self, id: I) -> Handle<T> where
I: Into<HandleId>,
T: Asset,
pub fn get_handle<I, T>(&self, id: I) -> Handle<T> where
I: Into<HandleId>,
T: Asset,
Gets a handle to an asset of type T
from its id.
pub async fn read_asset_bytes<P>(
&self,
path: P
) -> Result<Vec<u8, Global>, AssetIoError> where
P: AsRef<Path>,
pub async fn read_asset_bytes<P>(
&self,
path: P
) -> Result<Vec<u8, Global>, AssetIoError> where
P: AsRef<Path>,
Reads the contents of the file at the specified path through the AssetIo
associated
with this context.
