Struct x11rb_protocol::protocol::xproto::AllocColorRequest

pub struct AllocColorRequest {
    pub cmap: Colormap,
    pub red: u16,
    pub green: u16,
    pub blue: u16,
}

Allocate a color.

Allocates a read-only colormap entry corresponding to the closest RGB value supported by the hardware. If you are using TrueColor, you can take a shortcut and directly calculate the color pixel value to avoid the round trip. But, for example, on 16-bit color setups (VNC), you can easily get the closest supported RGB value to the RGB value you are specifying.

Fields

• cmap - TODO
• red - The red value of your color.
• green - The green value of your color.
• blue - The blue value of your color.

Errors

• Colormap - The specified colormap cmap does not exist.

Fields

cmap: Colormap

red: u16

green: u16

blue: u16

Implementations

impl AllocColorRequest

pub fn serialize(self) -> 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 AllocColorRequest

fn clone(&self) -> AllocColorRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AllocColorRequest

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

Formats the value using the given formatter.

impl Default for AllocColorRequest

fn default() -> AllocColorRequest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AllocColorRequest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for AllocColorRequest

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 AllocColorRequest

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

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

fn partial_cmp(&self, other: &AllocColorRequest) -> 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.

type Reply = AllocColorReply

The kind of reply that this request generates.

impl Request for AllocColorRequest

const EXTENSION_NAME: Option<&'static str> = None

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>>
