Ignoring Errors
# Simple Example
let res: Result<u8, ()> = Ok(42);
let opt: Option<u8> = res.ok();
println!("{:?}", opt);
# Nested Example
MsgSender::new(name.to_string())
.with_timepoint(sim_time(timestamp))
.with_component(&[Box3D::new(length / 2.0, width / 2.0, height / 2.0)]).ok()
.with_component(&[rerun_transform]).ok()
.with_component(&[ColorRGBA::from_rgb(r, g, b)]).ok()
.with_component(&[Radius(0.005)]).ok()
.with_component(&[Label(name.to_string().to_owned())]).ok()
.send(session).ok();Collecting Errors
# Nested Example - Get the First Error
