error[E0659]: `proconio` is ambiguous
--> src/main.rs:6:5
|
6 | use proconio::{
| ^^^^^^^^ ambiguous name
|
= note: ambiguous because of a conflict between a name from a glob import and an outer scope during import or macro resolution
= note: `proconio` could refer to a crate passed with `--extern`
= help: use `::proconio` to refer to this crate unambiguously
note: `proconio` could also refer to the module imported here
--> src/main.rs:1:9
|
1 | pub use __cargo_equip::prelude::*;
| ^^^^^^^^^^^^^^^^^^^^^^^^^
= help: consider adding an explicit import of `proconio` to disambiguate
= help: or use `crate::proconio` to refer to this module unambiguously
For more information about this error, try `rustc --explain E0659`.
error: could not compile `main` (bin "main") due to 1 previous error
