Struct Dst 

pub struct Dst<'a> {
    pub x0: i32,
    pub y0: i32,
    pub x1: i32,
    pub y1: i32,
    /* private fields */
}

the destination pixels of one render call: row k holds the pixels x0..x1 of row y0 + k

Fields

x0: i32

y0: i32

x1: i32

y1: i32

Implementations

impl<'a> Dst<'a>

pub fn new(roi: [i32; 4], rows: Vec<&'a mut [u8]>) -> Dst<'a>

a destination from row slices (each (x1 - x0) * 4 bytes, y1 - y0 of them)

pub fn strided(roi: [i32; 4], buf: &'a mut [u8], stride: usize) -> Dst<'a>

a destination in one buffer: row y0 + k at k * stride (e.g. a tile buffer with stride (x1 - x0) * 4)

pub fn of_surface(sf: &'a mut Surface, roi: [i32; 4]) -> Dst<'a>

the rectangle of a surface (clamped to it) as one destination

pub fn row(&mut self, y: i32) -> &mut [u8]

the pixels x0..x1 of row y (y0 <= y < y1)
