[−][src]Trait wayland_protocols::wlr::unstable::screencopy::v1::client::zwlr_screencopy_frame_v1::EventHandler
An interface for handling events.
Provided methods
fn buffer(
&mut self,
object: ZwlrScreencopyFrameV1,
format: u32,
width: u32,
height: u32,
stride: u32
)
&mut self,
object: ZwlrScreencopyFrameV1,
format: u32,
width: u32,
height: u32,
stride: u32
)
buffer information
Provides information about the frame's buffer. This event is sent once as soon as the frame is created.
The client should then create a buffer with the provided attributes, and send a "copy" request.
fn flags(&mut self, object: ZwlrScreencopyFrameV1, flags: Flags)
frame flags
Provides flags about the frame. This event is sent once before the "ready" event.
fn ready(
&mut self,
object: ZwlrScreencopyFrameV1,
tv_sec_hi: u32,
tv_sec_lo: u32,
tv_nsec: u32
)
&mut self,
object: ZwlrScreencopyFrameV1,
tv_sec_hi: u32,
tv_sec_lo: u32,
tv_nsec: u32
)
indicates frame is available for reading
Called as soon as the frame is copied, indicating it is available for reading. This event includes the time at which presentation happened at.
The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples, each component being an unsigned 32-bit value. Whole seconds are in tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo, and the additional fractional part in tv_nsec as nanoseconds. Hence, for valid timestamps tv_nsec must be in [0, 999999999]. The seconds part may have an arbitrary offset at start.
After receiving this event, the client should destroy the object.
fn failed(&mut self, object: ZwlrScreencopyFrameV1)
frame copy failed
This event indicates that the attempted frame copy has failed.
After receiving this event, the client should destroy the object.
