error[E0659]: `proconio` is ambiguous
 --> src/main.rs:5:5
  |
5 | 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
