pub struct JsFuture { /* private fields */ }Expand description
A Rust Future backed by a JavaScript Promise.
This type is constructed with a JavaScript Promise object and translates
it to a Rust Future. This type implements the Future trait from the
futures crate and will either succeed or fail depending on what happens
with the JavaScript Promise.
Currently this type is constructed with JsFuture::from.
