Struct Timing

    pub dot_clock_hz: f64,
    pub h_total: u32,
    pub h_active: u32,
    pub h_blank_start: u32,

    pub v_blank_end: u32,
    pub v_retrace_start: u32,
    pub v_retrace_end: u32,
}

Raster timing of the current video mode, in dots (pixel clock ticks) and scanlines.

Coordinates are relative to the first active dot of the first active line. A line runs 0..h_total: active display 0..h_active, right border up to h_blank_start, blanking (with horizontal retrace inside it) up to h_blank_end, and the next line’s left border up to h_total. Vertically the same: active 0..v_active, bottom border up to v_blank_start, blanking (with vertical retrace) up to v_blank_end, then the top border of the next frame up to v_total.

Fields

Implementations

impl Timing

pub fn normalized(self) -> Self

Clamp the values into a consistent order (registers can be programmed with nonsense).

pub fn line_rate_hz(&self) -> f64

Horizontal scan rate in Hz.

pub fn refresh_hz(&self) -> f64

Vertical refresh rate in Hz.

pub fn line_ns(&self) -> f64

Duration of one scanline in nanoseconds.

pub fn frame_ns(&self) -> f64

Duration of one frame in nanoseconds.

pub fn visible_size(&self) -> (u32, u32)

Size of the visible picture (active area plus overscan border) in dots x lines.

Trait Implementations
