Error code E0727
A yield
clause was used in an async
context.
Erroneous code example:
#![feature(coroutines)] fn main() { let coroutine = || { async { yield; } }; }
Here, the yield
keyword is used in an async
block,
which is not yet supported.
To fix this error, you have to move yield
out of the async
block:
#![feature(coroutines)] fn main() { let coroutine = || { yield; }; }
