Module clippy_utils::source

Utils for extracting, inspecting or transforming source code

Structs

• SourceFileRange

Traits

• IntoSpan
  Conversion of a value into a Span
• SpanRange
  Conversion of a value into the range portion of a Span.
• SpanRangeExt

Functions

• expand_past_previous_comma
  Expand a span to include a preceding comma
• expr_block
  Like snippet_block, but add braces if the expr is not an ExprKind::Block.
• first_char_in_first_line 🔒
• first_line_of_span
  Returns a new Span that extends the original Span to the first non-whitespace char of the first line.
• get_source_text 🔒
• indent_of
  Returns the indentation of the line of a span
• is_present_in_source
• line_span 🔒
  Extends the span to the beginning of the spans line, incl. whitespaces.
• map_range 🔒
• position_before_rarrow
  Returns the position just before rarrow
• reindent_multiline
  Reindent a multiline string with possibility of ignoring the first line.
• reindent_multiline_inner 🔒
• snippet
  Converts a span to a code snippet if available, otherwise returns the default.
• snippet_block
  Converts a span (from a block) to a code snippet if available, otherwise use default.
• snippet_block_with_applicability
  Same as snippet_block, but adapts the applicability level by the rules of snippet_with_applicability.
• snippet_block_with_context
• snippet_indent
  Gets a snippet of the indentation of the line of a span
• snippet_opt
  Converts a span to a code snippet. Returns None if not available.
• snippet_opt_sess 🔒
• snippet_with_applicability
  Same as snippet, but it adapts the applicability level by following rules:
• snippet_with_applicability_sess 🔒
• snippet_with_context
  Same as snippet_with_applicability, but first walks the span up to the given context. This will result in the macro call, rather than the expansion, if the span is from a child context. If the span is not from a child context, it will be used directly instead.
• snippet_with_context_sess 🔒
• str_literal_to_char_literal
  Converts expr to a char literal if it’s a str literal containing a single character (or a single byte with ascii_only)
• trim_span
  Trims the whitespace from the start and the end of the span.
• trim_start 🔒
• walk_span_to_context
  Walks the span up to the target context, thereby returning the macro call site if the span is inside a macro expansion, or the original span if it is not. Note this will return None in the case of the span being in a macro expansion, but the target context is from expanding a macro argument.
• with_leading_whitespace 🔒
• with_source_text 🔒
• with_source_text_and_range 🔒
• without_block_comments
  Removes block comments from the given Vec of lines.
• write_source_text_to 🔒
