class FrameInfo

Defined at line 338 of file fidling/gen/sdk/fidl/fuchsia.ui.composition.internal/fuchsia.ui.composition.internal/hlcpp/fuchsia/ui/composition/internal/cpp/fidl.h

Return fields of the [`GetNextFrame`] call. These fields hold the

frame’s information on buffer location, timing, and a way to release

after using it. All fields will be returned by the server.

const ::zx::eventpair & buffer_release_token ()

The release token for |buffer_index|. The client drops the eventpair

to signal to the server that |buffer_index| is free for writing.

If the eventpair is not dropped, then in the future calls to

[`GetNextFrame`], if there are no available buffers, the server will

wait until the client frees up a past buffer. If the client was holding

on to all buffers in the buffer collection and then

releases a buffer while hanging, the server will immediately return the

latest frame.
