About Rust Formatting
This tool helps you auto-beautify Rust code:
β’ Auto Indentation β Detects code block nesting levels
β’ Brace Style β K&R (same-line {) or Allman (next-line {)
β’ Operator Spacing β Adds proper spaces around operators
β’ Blank Line Cleanup β Removes consecutive blank lines
β’ Trailing Whitespace β Removes stray spaces at line ends
Note: This tool provides basic formatting without complex AST analysis. All computation happens on your device.
Frequently Asked Questions (FAQ)
Will formatting change my code's logic?
No. Formatting only adjusts whitespace and layout. The code remains functionally identical.
What's the difference between K&R and Allman brace styles?
K&R places the opening brace on the same line (if (x) {), while Allman places it on a new line. Both are valid; it's a matter of preference.
Which syntax features are supported?
Supports basic Rust syntax structures including functions, structs, and control flow. For complex nesting, consider using an IDE formatter.
