[][src]Struct wayland_protocols::presentation_time::server::wp_presentation_feedback::Kind

pub struct Kind { /* fields omitted */ }

bitmask of flags in presented event

These flags provide information about how the presentation of the related content update was done. The intent is to help clients assess the reliability of the feedback and the visual quality with respect to possible tearing and timings. The flags are:

VSYNC: The presentation was synchronized to the "vertical retrace" by the display hardware such that tearing does not happen. Relying on user space scheduling is not acceptable for this flag. If presentation is done by a copy to the active frontbuffer, then it must guarantee that tearing cannot happen.

HW_CLOCK: The display hardware provided measurements that the hardware driver converted into a presentation timestamp. Sampling a clock in user space is not acceptable for this flag.

HW_COMPLETION: The display hardware signalled that it started using the new image content. The opposite of this is e.g. a timer being used to guess when the display hardware has switched to the new image content.

ZERO_COPY: The presentation of this update was done zero-copy. This means the buffer from the client was given to display hardware as is, without copying it. Compositing with OpenGL counts as copying, even if textured directly from the client buffer. Possible zero-copy cases include direct scanout of a fullscreen surface and a surface on a hardware overlay.

Implementations

impl Kind[src]

pub const Vsync: Kind[src]

presentation was vsync'd

pub const HwClock: Kind[src]

hardware provided the presentation timestamp

pub const HwCompletion: Kind[src]

hardware signalled the start of the presentation

pub const ZeroCopy: Kind[src]

pub const fn empty() -> Kind[src]

Returns an empty set of flags

pub const fn all() -> Kind[src]

Returns the set containing all flags.

pub const fn bits(&self) -> u32[src]

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<Kind>[src]

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> Kind[src]

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> Kind[src]

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool[src]

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool[src]

Returns true if all flags are currently set.

pub const fn intersects(&self, other: Kind) -> bool[src]

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: Kind) -> bool[src]

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: Kind)[src]

Inserts the specified flags in-place.

pub fn remove(&mut self, other: Kind)[src]

Removes the specified flags in-place.

pub fn toggle(&mut self, other: Kind)[src]

Toggles the specified flags in-place.

pub fn set(&mut self, other: Kind, value: bool)[src]

Inserts or removes the specified flags depending on the passed value.
