Add compiler hint for stdin().get_line() -> stdin().read_line()

[myclevorname]

Code

I am learning Rust, and I keep typing std::io::stdin().get_line() instead of std::io::stdin().read_line() and the compiler doesn't give any useful hints.

Current output

   Compiling playground v0.0.1 (/playground)
error[E0599]: no method named `get_line` found for struct `Stdin` in the current scope
 --> src/main.rs:5:13
  |
5 |     stdin().get_line(&mut string);
  |             ^^^^^^^^ method not found in `Stdin`

Desired output

   Compiling playground v0.0.1 (/playground)
error[E0599]: no method named `get_line` found for struct `Stdin` in the current scope
 --> src/main.rs:5:13
  |
5 |     stdin().get_line(&mut string);
  |             ^^^^^^^^
  |
help: there is a method `read_line` with a similar name
  |
5 |     stdin().read_line(&mut string);
  |             ~~~~~~~~~

Rationale and extra context

I keep accidentally making this mistake because I am a beginner.

Rust Version

rustc version 1.81.0 via https://play.rust-lang.org/?version=stable&mode=debug&edition=2021
I am not able to access my laptop right now, and it uses 1.80.1 anyway.

Anything else?

I think putting #[doc(alias = "get_line")] on read_line() should be enough for that.

[GrigorenkoPV]

I tried slapping #[rustc_confusables("read_line")] onto it, but it only seems to support inherent methods.

[ChayimFriedman2]

@GrigorenkoPV It is an inherent method though? (Though not for StdinLock).

[GrigorenkoPV]

Oh, yes, you are right. I did confuse it with BufRead's one for StdinLock.
