pub struct AsyncFunction(/* private fields */);
Expand description

An asynchronous Rust function that can be stored in a Value and called.

Implementations§

source§

impl AsyncFunction

source

pub fn new<F, Fut>(function: F) -> Self
where F: Fn(&mut VmContext<'_, '_>, Arity) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<Value, Fault>> + Send + Sync + 'static,

Returns a new function that invokes function and awaits the returned future when called.
