Implementations

impl Angle

pub fn offscreen( dir: &Path, w: u32, h: u32, software: bool, ) -> Result<Angle, String>

An offscreen context of w×h (headless screenshots).

pub fn window( dir: &Path, window: NativeWindow, software: bool, ) -> Result<Angle, String>

A context drawing into window.

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

The surface size in pixels (a window surface follows the window).

pub fn show_image(&self, rgba: &[u8], w: u32, h: u32)

Show an RGBA8 image (rows top to bottom) letterboxed on black and swap: the runner’s own frames (the splash) before the game draws. Leaves no GL state behind that the game could see (its objects are deleted, bindings reset to 0).

pub fn show_image_over_game(&self, rgba: &[u8], w: u32, h: u32)

Angle::show_image while a game runs (the consent question): the GL state it changes is put back, so the game’s next frame sees what it left.

pub fn swap(&self)

pub fn make_current(&self)

pub fn read_frame(&self) -> (u32, u32, Vec<u8>)

The default framebuffer as RGBA8 rows, top to bottom.

Trait Implementations

impl Drop for Angle

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
