Struct SuspendedContext

Source
pub struct SuspendedContext(/* private fields */);
Expand description

A suspended imgui-rs context.

A suspended context retains its state, but is not usable without activating it first.

§Examples

Suspended contexts are not directly very useful, but you can activate them:

let suspended = imgui::SuspendedContext::create();
match suspended.activate() {
  Ok(ctx) => {
    // ctx is now the active context
  },
  Err(suspended) => {
    // activation failed, so you get the suspended context back
  }
}

Implementations§

Source§

impl SuspendedContext

Source

pub fn create() -> SuspendedContext

Creates a new suspended imgui-rs context.

Source

pub fn create_with_shared_font_atlas( shared_font_atlas: SharedFontAtlas, ) -> SuspendedContext

Creates a new suspended imgui-rs context with a shared font atlas.

Source

pub fn activate(self) -> Result<Context, SuspendedContext>

Attempts to activate this suspended context.

If there is no active context, this suspended context is activated and Ok is returned, containing the activated context. If there is already an active context, nothing happens and Err is returned, containing the original suspended context.
