Error code E0752
The entry point of the program was marked as async
.
Erroneous code example:
async fn main() -> Result<(), ()> { // error! Ok(()) }
fn main()
or the specified start function is not allowed to be async
. Not
having a correct async runtime library setup may cause this error. To fix it,
declare the entry point without async
:
fn main() -> Result<(), ()> { // ok! Ok(()) }
