Module parsel::util

Helper functions, types and macros that didn’t fit anywhere else.

Structs

• SpanDisplay
  Helper type that formats a Span in a human-readable way.
• TokenStreamFormatter
  Helper type for correctly and reasonably “pretty”-printing any TokenStream in a grammar- and language-agnostic way. This mostly means dealing with parentheses, so that nested structures don’t end up on one single long line.

Traits

• SpannedExt
  Extension trait for formatting the span of AST nodes in a human-readable manner, and for (re-)computing byte offsets into the source based on the line/column location, since this information is not exposed by the public API of Span.

Functions

• pretty_print_tokens
  Helper for implementing Display in terms of ToTokens.
