Struct quad_wasmnastics::waiter::Waiter [−][src]
pub struct Waiter<T> { /* fields omitted */ }Expand description
Something that is waiting on a value from Javascript.
Implementations
impl<T: MaybeFromJsObject> Waiter<T>[src]
impl<T: MaybeFromJsObject> Waiter<T>[src]pub fn new_immediate(val: T) -> Self[src]
pub fn new_immediate(val: T) -> Self[src]Make a new Waiter with an immediate value.
pub fn new_empty() -> Self[src]
pub fn new_empty() -> Self[src]Make a new Waiter that will never return Some, in case you wanted to do that for some reason.
pub fn try_get(&mut self) -> Option<T>[src]
pub fn try_get(&mut self) -> Option<T>[src]Try and get the value from this.
You shouldn’t write your code relying on this to return anytime soon. On desktop it might, but it may take several frames on the web. Probably best to assume for the worst.
This will never return Some if the conversion from JS fails, or if
something else wrong happens in JS, like no waiting field.
(The JS API will try and print any exceptions to the console but you can’t
rely on it from Rust.)
Once this returns Some once, it will never return Some again (for a specific Waiter).
The value will have moved out of it.
