* surface.acquire_texture: pass Option<Duration> for timeout A std::time::Duration allows for timeouts to be specified more clearly in Rust using whatever units are convenient for the caller, and an Option also makes it clearer in case no timeout is wanted, as opposed to passing a bitwise !0 as special timeout value. Notably there was an impedance mismatch with the Vulkan backend that takes a 64bit timeout in nanoseconds and uses u64::MAX to indicate no timeout and the backend was not mapping a given u32::MAX into a u64::MAX * surface.acquire_texture: ignore timeout for Android < 11 Prior to Android 11 then Android's vkAcquireNextImageKHR implementation was non-conformant and didn't support timeouts and additionally would log a verbose warning if a timeout was requested. For reference this version of AcquireNextImageKHR doesn't support timeouts: https://android.googlesource.com/platform/frameworks/native/+/refs/tags/android-mainline-10.0.0_r13/vulkan/libvulkan/swapchain.cpp#1426 and this version does: https://android.googlesource.com/platform/frameworks/native/+/refs/tags/android-mainline-11.0.0_r45/vulkan/libvulkan/swapchain.cpp#1438 (i.e. timeout support was added in Android 11) This patch adds a dependency on the `android-properties` crate that provides a simple wrapper for the `__system_property_set` syscall so that the platform version can be read via the `ro.build.version.sdk` property and then for versions < 30 (corresponds to Android 11) any timeout given to `acquire_texture` will be ignored (and `u64::MAX` will be passed to Vulkan) |
