src/tools/clippy/src/docs/tabs_in_doc_comments.txt

   1 ### What it does
   2 Checks doc comments for usage of tab characters.
   3
   4 ### Why is this bad?
   5 The rust style-guide promotes spaces instead of tabs for indentation.
   6 To keep a consistent view on the source, also doc comments should not have tabs.
   7 Also, explaining ascii-diagrams containing tabs can get displayed incorrectly when the
   8 display settings of the author and reader differ.

  10 ### Example
  11 ```
  12 ///
  13 /// Struct to hold two strings:
  14 ///     - first         one
  15 ///     - second        one
  16 pub struct DoubleString {
  17    ///
  18    ///  - First String:
  19    ///          - needs to be inside here
  20    first_string: String,
  21    ///
  22    ///  - Second String:
  23    ///          - needs to be inside here
  24    second_string: String,
  25 }
  26 ```
  27
  28 Will be converted to:
  29 ```
  30 ///
  31 /// Struct to hold two strings:
  32 ///     - first        one
  33 ///     - second    one
  34 pub struct DoubleString {
  35    ///
  36    ///     - First String:
  37    ///         - needs to be inside here
  38    first_string: String,
  39    ///
  40    ///     - Second String:
  41    ///         - needs to be inside here
  42    second_string: String,
  43 }
