frust_render/native_import/
mod.rs

1//! Platform importers for the external-texture frame bus: the per-platform
2//! [`NativeImporter`](crate::texture_bus::NativeImporter) implementations that
3//! wrap a `frust-gpu` zero-copy import (a CVPixelBuffer on Apple, an
4//! AHardwareBuffer on Android) so a plugin's native frame draws as a scene
5//! texture without a copy. Each platform half lives behind its own `cfg`; on
6//! every other target the module is empty and [`install`] is a no-op.
