Feature Request: Folding regions for Rust

[PaulHale]

Folding regions for Rust

The following languages currently have markers defined:

TypeScript/JavaScript: //#region and //#endregion and //region and //endregion
C#: #region and #endregion
C/C++: #pragma region and #pragma endregion
F#: //#region and //#endregion
Powershell: #region and #endregion
VB: #Region and #End Region
CSS/Less/SCSS: /*#region*/ and /*#endregion*/
Coffeescript: #region and #endregion
PHP: #region and #endregion
Bat: ::#region and ::#endregion

Can we please have this functionality for Rust code?
Rust: #region and #endregion would suffice

Thanks for submitting this issue. Please also check if it is already covered by an existing one, like:

• [folding] select line with folding should include folded range (#51232)
• [folding] Hover can show region description on #endregion (#38149)
• region navigator (#51738)
• #region and #endregion last state is not saved (#42217)
• Typescript region folding does not work when syntax-aware folding is enabled (#52650)

This works for me nicely if the #region and #endregion are indented all the way to the left. However if they are a bit indented it does not work. @aeschli is this expected?
Here's an example where it is not working (notice the indentation)

fn main() {
    // The statements here will be executed when the compiled binary is called

	#region
 	///my region
	#endregion

    // Print text to the console
    println!("Hello World!");
}

Sounds like a bug to me.

@isidorn it does work if the code within the #region #endregion is also indented. Kind of forces you to indent your code within regions which I personally like. Not sure if this is by design though.

[aeschli]

The PR added only// region and // endregion as folding regions. For consistency we should also support // #region and // #endregion. That was the original request and what @isidorn tried.
