The `get_first` lint is applied to VecDeque but the help only mentions `first()`and not `front()`

[HEnquist]

Description

The help text for the get_first lint assumes that first() is the method to use instead of get(0), but this does not exist for a VecDeque. There, the front() method is the equivalent.
The text is defined here:

rust-clippy/clippy_lints/src/methods/mod.rs

Line 2596 in 7f185bd

/// Using `x.first()` is easier to read and has the same

I'm assuming that the text was written before the lint was applied also to VecDeque, but now it's a bit misleading.

The suggestion however is correct, example:
help: try: self.buffer.front()`

Thanks for your report. Could you provide a complete reproducer? The code below:

fn main() {
    let v = std::collections::VecDeque::from_iter([0]);
    v.get(0).unwrap();
}

produces the proper warning with Clippy's master branch:

warning: accessing first element with `v.get(0)`
 --> /tmp/t.rs:3:5
  |
3 |     v.get(0).unwrap();
  |     ^^^^^^^^ help: try: `v.front()`

  = note: `#[warn(clippy::get_first)]` on by default

Ah sorry my description was unclear, clippy gives the right suggestion! The issue is only in the linked web page: https://rust-lang.github.io/rust-clippy/master/index.html#get_first
