Struct PolyLineRequest

pub struct PolyLineRequest<'input> {
    pub coordinate_mode: CoordMode,
    pub drawable: Drawable,
    pub gc: Gcontext,
    pub points: Cow<'input, [Point]>,
}

draw lines.

Draws points_len-1 lines between each pair of points (point[i], point[i+1]) in the points array. The lines are drawn in the order listed in the array. They join correctly at all intermediate points, and if the first and last points coincide, the first and last lines also join correctly. For any given line, a pixel is not drawn more than once. If thin (zero line-width) lines intersect, the intersecting pixels are drawn multiple times. If wide lines intersect, the intersecting pixels are drawn only once, as though the entire request were a single, filled shape.

Fields

• drawable - The drawable to draw the line(s) on.
• gc - The graphics context to use.
• points_len - The number of xcb_point_t structures in points.
• points - An array of points.
• coordinate_mode -

Errors

• Drawable - TODO: reasons?
• GContext - TODO: reasons?
• Match - TODO: reasons?
• Value - TODO: reasons?

Trait Implementations

impl<'input> Clone for PolyLineRequest<'input>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'input> Debug for PolyLineRequest<'input>

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

Formats the value using the given formatter.

impl<'input> Default for PolyLineRequest<'input>

fn default() -> PolyLineRequest<'input>

Returns the “default value” for a type.

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'input> Hash for PolyLineRequest<'input>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)
