Struct AllocateBackBufferRequest 

pub struct AllocateBackBufferRequest {
    pub window: u32,
    pub buffer: u32,
    pub swap_action: u8,
}

Allocates a back buffer.

Associates buffer with the back buffer of window. Multiple ids may be associated with the back buffer, which is created by the first allocate call and destroyed by the last deallocate.

Fields

• window - The window to which to add the back buffer.
• buffer - The buffer id to associate with the back buffer.
• swap_action - The swap action most likely to be used to present this back buffer. This is only a hint, and does not preclude the use of other swap actions.

Fields

window: u32

buffer: u32

swap_action: u8

Implementations

impl AllocateBackBufferRequest

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

Serialize this request into bytes for the provided connection

Trait Implementations

impl Clone for AllocateBackBufferRequest

fn clone(&self) -> AllocateBackBufferRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllocateBackBufferRequest

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

Formats the value using the given formatter.

impl Default for AllocateBackBufferRequest

fn default() -> AllocateBackBufferRequest

Returns the “default value” for a type.

impl Hash for AllocateBackBufferRequest

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

where __H: Hasher,

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 AllocateBackBufferRequest

fn cmp(&self, other: &AllocateBackBufferRequest) -> 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,

Restrict a value to a certain interval.

impl PartialEq for AllocateBackBufferRequest

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for AllocateBackBufferRequest

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Request for AllocateBackBufferRequest

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) -> (Vec<u8>, Vec<OwnedFd>)

Serialize this request into its X11 protocol wire representation.
