Module tidy::style

Tidy check to enforce various stylistic guidelines on the Rust codebase.

Example checks are:

• No lines over 100 characters (in non-Rust files).
• No files with over 3000 lines (in non-Rust files).
• No tabs.
• No trailing whitespace.
• No CR characters.
• No TODO or XXX directives.
• No unexplained ```ignore or ```rust,ignore doc tests.

Note that some of these rules are excluded from Rust files because we enforce rustfmt. It is preferable to be formatted rather than tidy-clean.

A number of these checks can be opted-out of with various directives of the form: // ignore-tidy-CHECK-NAME.

Macros

Enums

• Directive 🔒
• LIUState 🔒
  Parser states for line_is_url.

Constants

• ANNOTATIONS_TO_IGNORE 🔒
• COLS 🔒
• DOUBLE_SPACE_AFTER_DOT 🔒
• ERROR_CODE_COLS 🔒
  Error code markdown is restricted to 80 columns because they can be displayed on the console with –example.
• GOML_COLS 🔒

Functions

• check
• contains_ignore_directive 🔒
• generate_problematic_strings 🔒
• generate_problems 🔒
• is_in
• is_unexplained_ignore 🔒
• line_is_url 🔒
  Returns true if line appears to be a line comment containing a URL, possibly with a Markdown link label in front, and nothing else. The Markdown link label, if present, may not contain whitespace. Lines of this form are allowed to be overlength, because Markdown offers no way to split a line in the middle of a URL, and the lengths of URLs to external references are beyond our control.
• long_line_is_ok 🔒
  Returns true if line is allowed to be longer than the normal limit.
• should_ignore 🔒
  Returns true if line can be ignored. This is the case when it contains an annotation that is explicitly ignored.
• skip_markdown_path 🔒
