Struct Display 

pub struct Display<Api = Default>(/* private fields */);

Implementations

impl Display<Default>

pub fn Default() -> Self

Creates default Display without type parameter requirement.

Uses ZST api::Default.

impl Display<Cache>

pub fn Cached() -> Self

Creates Display without type parameter requirement.

Uses api::Cache.

impl<Api: Default + Api> Display<Api>

pub fn new() -> Self

impl<Api: Api> Display<Api>

pub fn new_with(api: Api) -> Self

impl Display<Default>

pub const COLUMNS: u32 = 400u32

pub const ROWS: u32 = 240u32

pub const ROW_SIZE: u32 = 52u32

pub const SCREEN_RECT: LCDRect

impl<Api: Api> Display<Api>

pub fn width(&self) -> c_int

Returns the width of the display, taking the current scale into account;

e.g., if the scale is 2, this function returns 200 instead of 400.

See also Display::COLUMNS.

Equivalent to sys::ffi::playdate_display::getWidth

pub fn height(&self) -> c_int

Returns the height of the display, taking the current scale into account;

e.g., if the scale is 2, this function returns 120 instead of 240.

See also Display::ROWS and Display::ROW_SIZE.

Equivalent to sys::ffi::playdate_display::getHeight

pub fn set_refresh_rate(&self, rate: c_float)

Sets the nominal refresh rate in frames per second.

Default is 20 fps, the maximum rate supported by the hardware for full-frame updates.

Equivalent to sys::ffi::playdate_display::setRefreshRate

pub fn set_inverted(&self, value: bool)

If value is true, the frame buffer is drawn inverted—black instead of white, and vice versa.

Equivalent to sys::ffi::playdate_display::setInverted

pub fn set_scale(&self, scale: DisplayScale)

Sets the display scale factor.

The top-left corner of the frame buffer is scaled up to fill the display;

e.g., if the scale is set to DisplayScale::Quad, the pixels in rectangle [0, 100] x [0, 60] are drawn on the screen as 4 x 4 squares.

Equivalent to sys::ffi::playdate_display::setScale

pub fn set_scale_raw(&self, scale: c_uint)

Sets the display scale factor.

Valid values for scale are 1, 2, 4, and 8.

The top-left corner of the frame buffer is scaled up to fill the display; e.g., if the scale is set to 4, the pixels in rectangle [0, 100] x [0, 60] are drawn on the screen as 4 x 4 squares.

See also Display::set_scale.

Equivalent to sys::ffi::playdate_display::setScale

pub fn set_mosaic(&self, x: c_uint, y: c_uint)

Adds a mosaic effect to the display.

Valid x and y values are between 0 and 3, inclusive.

Equivalent to sys::ffi::playdate_display::setMosaic

pub fn set_flipped(&self, x: bool, y: bool)

Flips the display on the x or y axis, or both.

Equivalent to sys::ffi::playdate_display::setFlipped

pub fn set_offset(&self, x: c_int, y: c_int)

Offsets the display by the given amount.

Areas outside of the displayed area are filled with the current background color.

See also [playdate-graphics::set_background_color].

Equivalent to sys::ffi::playdate_display::setOffset

Trait Implementations

impl<Api: Clone> Clone for Display<Api>

fn clone(&self) -> Display<Api>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Api: Debug> Debug for Display<Api>

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

Formats the value using the given formatter.

impl<Api: Default + Api> Default for Display<Api>

fn default() -> Self

Returns the “default value” for a type.

impl<Api: Copy> Copy for Display<Api>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
