Struct x11rb_protocol::protocol::shm::CreateSegmentRequest

pub struct CreateSegmentRequest {
    pub shmseg: Seg,
    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: Seg

size: u32

read_only: bool

Implementations

impl CreateSegmentRequest

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 CreateSegmentRequest

fn clone(&self) -> CreateSegmentRequest

Returns a copy 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

Formats the value using the given formatter.

impl Default for CreateSegmentRequest

fn default() -> CreateSegmentRequest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CreateSegmentRequest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for CreateSegmentRequest

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 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for CreateSegmentRequest

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

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 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) -> BufWithFds<Vec<u8>>

Serialize this request into its X11 protocol wire representation.

impl Serialize for CreateSegmentRequest

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
