Expand description

A native AAssetManager *.

Implementations§

Source§

impl AssetManager

Source

pub unsafe fn from_ptr(ptr: NonNull<AAssetManager>) -> Self

Create an AssetManager from a pointer

By calling this function, you assert that the pointer is a valid pointer to a native AAssetManager.

Source

pub fn ptr(&self) -> NonNull<AAssetManager>

Returns the pointer to the native AAssetManager.

Source

pub fn open(&self, filename: &CStr) -> Option<Asset>

Open the asset. Returns None if opening the asset fails.

This currently always opens the asset in the streaming mode.

Source

pub fn open_dir(&self, filename: &CStr) -> Option<AssetDir>

Open an asset directory. Returns None if opening the directory fails.
