Copy data from the shared memory to the specified drawable..

Copy data from the shared memory to the specified drawable. The amount of bytes written to the destination image is always equal to the number of bytes read from the shared memory segment.

Fields

• drawable - The drawable to draw to.
• gc - The graphics context to use.
• total_width - The total width of the source image.
• total_height - The total height of the source image.
• src_x - The source X coordinate of the sub-image to copy.
• src_y - The source Y coordinate of the sub-image to copy.
• src_width - The width, in source image coordinates, of the data to copy from the source. The X server will use this to determine the amount of data to copy. The amount of the destination image that is overwritten is determined automatically.
• src_height - The height, in source image coordinates, of the data to copy from the source. The X server will use this to determine the amount of data to copy. The amount of the destination image that is overwritten is determined automatically.
• dst_x - The X coordinate on the destination drawable to copy to.
• dst_y - The Y coordinate on the destination drawable to copy to.
• depth - The depth to use.
• format - The format of the image being drawn. If it is XYBitmap, depth must be 1, or a “BadMatch” error results. The foreground pixel in the GC determines the source for the one bits in the image, and the background pixel determines the source for the zero bits. For XYPixmap and ZPixmap, the depth must match the depth of the drawable, or a “BadMatch” error results.
• send_event - True if the server should send an XCB_SHM_COMPLETION event when the blit completes.
• offset - The offset that the source image starts at.

Implementations

impl PutImageRequest

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

Serialize this request into bytes for the provided connection

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

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

Trait Implementations

impl Clone for PutImageRequest

fn clone(&self) -> PutImageRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PutImageRequest

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

Formats the value using the given formatter.

impl Default for PutImageRequest

fn default() -> PutImageRequest

Returns the “default value” for a type.

impl Hash for PutImageRequest

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 PutImageRequest

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

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

fn partial_cmp(&self, other: &PutImageRequest) -> 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 PutImageRequest

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.
