Struct CreateSegmentRequest

pub struct CreateSegmentRequest {
    pub shmseg: u32,
    pub size: u32,
    pub read_only: bool,
}

Asks the server to allocate a shared memory segment..

Asks the server to allocate a shared memory segment. The server’s reply will include a file descriptor for the client to pass to mmap().

Fields

• shmseg - A shared memory segment ID created with xcb_generate_id().
• size - The size of the segment to create.
• read_only - True if the server should map the segment read-only; otherwise false.

Fields

shmseg: u32

size: u32

read_only: bool

Implementations

impl CreateSegmentRequest

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 CreateSegmentRequest

fn clone(&self) -> CreateSegmentRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CreateSegmentRequest

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

Formats the value using the given formatter.

impl Default for CreateSegmentRequest

fn default() -> CreateSegmentRequest

Returns the “default value” for a type.

impl Hash for CreateSegmentRequest

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 CreateSegmentRequest

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

fn eq(&self, other: &CreateSegmentRequest) -> 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 CreateSegmentRequest

fn partial_cmp(&self, other: &CreateSegmentRequest) -> 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 ReplyFDsRequest for CreateSegmentRequest

type Reply = CreateSegmentReply

The kind of reply that this request generates.

impl Request for CreateSegmentRequest

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.
