Struct ux::prelude::dx::FrameInfo [−][src]
pub struct FrameInfo(_, _);
Implementations
impl FrameInfo
[src]
impl FrameInfo
[src]pub fn get_frame_counter(&self) -> i64
[src]
Gets the frame counter for the Onscreen
that corresponds
to this frame.
Returns
The frame counter value
pub fn get_output(&self) -> Option<Output>
[src]
Gets the Output
that the swapped frame was presented to.
Returns
The Output
that the frame was
presented to, or None
if this could not be determined.
pub fn get_presentation_time(&self) -> i64
[src]
Gets the presentation time for the frame. This is the time at which the frame became visible to the user.
The presentation time measured in nanoseconds is based on a monotonic time source. The time source is not necessarily correlated with system/wall clock time and may represent the time elapsed since some undefined system event such as when the system last booted.
<note>
Linux kernel version less that 3.8 can result in
non-monotonic timestamps being reported when using a drm based
OpenGL driver. Also some buggy Mesa drivers up to 9.0.1 may also
incorrectly report non-monotonic timestamps.</note>
Returns
the presentation time for the frame
pub fn get_refresh_rate(&self) -> f32
[src]
Gets the refresh rate in Hertz for the output that the frame was on at the time the frame was presented.
<note>
Some platforms can’t associate a Output
with a
FrameInfo
object but are able to report a refresh rate via
this api. Therefore if you need this information then this api is
more reliable than using FrameInfo::get_output
followed by
Output::get_refresh_rate
.</note>
Returns
the refresh rate in Hertz
