# Description
|
|
|
|
|
|
|
|
|
|
readcy[^1] creates a future that is immediately ready with a value.
|
|
|
|
|
|
|
|
|
|
Futures created through this function are functionally similar to those
|
|
|
|
|
created through `async {}`. The main difference is that futures created
|
|
|
|
|
through this function are named and implement `Unpin`.
