Struct Gl 

pub struct Gl {
    pub stats: Option<GlStats>,
    /* private fields */
}

The gasm:gl state of one guest (model + null GL).

Fields

stats: Option<GlStats>

--gl-stats: calls by name, printed when the game ends

Implementations

impl Gl

pub fn attach(&mut self, angle: Angle)

Execute calls on ANGLE from now on (the model stays in front of it).

pub fn has_backend(&self) -> bool

pub fn end_frame(&mut self, show: bool)

The frame ended: show it if show (unless the guest did with present()).

pub fn show_over_game(&self, rgba: &[u8], w: u32, h: u32) -> bool

Show an image instead of the game’s frame, leaving the game’s GL state as it was (the consent question). False without ANGLE.

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

The default framebuffer as RGBA8, top to bottom (headless screenshots).

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

The drawable size, if a backend draws.

pub fn renderer(&self) -> Option<&str>

Trait Implementations

impl Default for Gl
