[−][src]Struct stdweb::Mut
A wrapper for passing FnMut
callbacks into the js!
macro.
Just like when passing regular Fn
callbacks, don't forget
to drop()
them on the JavaScript side or else the closure
will be leaked.
Examples
let mut count = 0; let callback = move || { count += 1; println!( "Callback called {} times", count ); }; js! { var cb = @{Mut(callback)}; cb(); cb(); cb(); cb.drop(); }
