Struct x11rb_protocol::protocol::damage::CreateRequest

pub struct CreateRequest {
    pub damage: Damage,
    pub drawable: Drawable,
    pub level: ReportLevel,
}

Creates a Damage object to monitor changes to a drawable..

This creates a Damage object to monitor changes to a drawable, and specifies the level of detail to be reported for changes.

We call changes made to pixel contents of windows and pixmaps ‘damage’ throughout this extension.

Damage accumulates as drawing occurs in the drawable. Each drawing operation ‘damages’ one or more rectangular areas within the drawable. The rectangles are guaranteed to include the set of pixels modified by each operation, but may include significantly more than just those pixels. The desire is for the damage to strike a balance between the number of rectangles reported and the extraneous area included. A reasonable goal is for each primitive object drawn (line, string, rectangle) to be represented as a single rectangle and for the damage area of the operation to be the union of these rectangles.

The DAMAGE extension allows applications to either receive the raw rectangles as a stream of events, or to have them partially processed within the X server to reduce the amount of data transmitted as well as reduce the processing latency once the repaint operation has started.

The Damage object holds any accumulated damage region and reflects the relationship between the drawable selected for damage notification and the drawable for which damage is tracked.

Fields

• damage - The ID with which you will refer to the new Damage object, created by xcb_generate_id.
• drawable - The ID of the drawable to be monitored.
• level - The level of detail to be provided in Damage events.

Fields

damage: Damage

drawable: Drawable

level: ReportLevel

Implementations

impl CreateRequest

pub fn serialize(self, major_opcode: u8) -> BufWithFds<[Cow<'static, [u8]>; 1]>

Serialize this request into bytes for the provided connection

pub fn try_parse_request( header: RequestHeader, value: &[u8] ) -> Result<Self, ParseError>

Parse this request given its header, its body, and any fds that go along with it

Trait Implementations

impl Clone for CreateRequest

fn clone(&self) -> CreateRequest

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CreateRequest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CreateRequest

fn default() -> CreateRequest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CreateRequest

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for CreateRequest

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CreateRequest

fn cmp(&self, other: &CreateRequest) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for CreateRequest

fn eq(&self, other: &CreateRequest) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for CreateRequest

fn partial_cmp(&self, other: &CreateRequest) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Request for CreateRequest

const EXTENSION_NAME: Option<&'static str> = _

The protocol name of the extension that this request belongs to, or None for core requests

fn serialize(self, major_opcode: u8) -> BufWithFds<Vec<u8>>

Serialize this request into its X11 protocol wire representation.

impl Serialize for CreateRequest

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
