Struct x11rb::protocol::xproto::ImageText16Request

pub struct ImageText16Request<'input> {
    pub drawable: u32,
    pub gc: u32,
    pub x: i16,
    pub y: i16,
    pub string: Cow<'input, [Char2b]>,
}

Draws text.

Fills the destination rectangle with the background pixel from gc, then paints the text with the foreground pixel from gc. The upper-left corner of the filled rectangle is at [x, y - font-ascent]. The width is overall-width, the height is font-ascent + font-descent. The overall-width, font-ascent and font-descent are as returned by xcb_query_text_extents (TODO).

Note that using X core fonts is deprecated (but still supported) in favor of client-side rendering using Xft.

Fields

• drawable - The drawable (Window or Pixmap) to draw text on.
• string - The string to draw. Only the first 255 characters are relevant due to the data type of string_len. Every character uses 2 bytes (hence the 16 in this request’s name).
• x - The x coordinate of the first character, relative to the origin of drawable.
• y - The y coordinate of the first character, relative to the origin of drawable.
• gc - The graphics context to use.

The following graphics context components are used: plane-mask, foreground, background, font, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask.

Errors

• Drawable - The specified drawable (Window or Pixmap) does not exist.
• GContext - The specified graphics context does not exist.
• Match - TODO: reasons?

Clone all borrowed data in this ImageText16Request.

Trait Implementations

impl<'input> Clone for ImageText16Request<'input>

fn clone(&self) -> ImageText16Request<'input>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'input> Debug for ImageText16Request<'input>

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

Formats the value using the given formatter.

impl<'input> Default for ImageText16Request<'input>

fn default() -> ImageText16Request<'input>

Returns the “default value” for a type.

impl<'input> Hash for ImageText16Request<'input>

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<'input> Ord for ImageText16Request<'input>

fn cmp(&self, other: &ImageText16Request<'input>) -> 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<'input> PartialEq for ImageText16Request<'input>

fn eq(&self, other: &ImageText16Request<'input>) -> 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.

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.
