FrameCallback

vmb_core::callback

Struct FrameCallback 

Source 
pub struct FrameCallback { /* private fields */ }
Expand description

User-provided frame callback, type-erased into a boxed trait object.

The closure is higher-rank over the frame lifetime: it accepts a &Frame<'a> for any 'a, which matches how adapters conjure up a fresh lifetime on every invocation.

Implementations§

Source§

impl FrameCallback

Source

pub fn new<F>(f: F) -> Self
where F: for<'a> Fn(&Frame<'a>) + Send + Sync + 'static,

Wrap a closure.

Source

pub fn invoke(&self, frame: &Frame<'_>)

Invoke the closure with the given frame. Called by adapters.
