Crate syntax_bridge

Conversions between [SyntaxNode] and [tt::TokenTree].

Modules

• dummy_test_span_utils
  Dummy things for testing where spans don’t matter.
• prettify_macro_expansion
  Utilities for formatting macro expanded nodes until we get a proper formatter.

Enums

• DocCommentDesugarMode
  Doc comment desugaring differs between mbe and proc-macros.
• TopEntryPoint
  Parse the whole of the input as a given syntactic construct.

Traits

• SpanMapper

Functions

• desugar_doc_comment_text
  Returns the textual content of a doc comment block as a quoted string That is, strips leading /// (or /**, etc) and strips the ending */ And then quote the string, which is needed to convert to tt::Literal
• parse_to_token_tree
  Convert a string to a TokenTree. The spans of the subtree will be anchored to the provided anchor with the given context.
• parse_to_token_tree_static_span
  Convert a string to a TokenTree. The passed span will be used for all spans of the produced subtree.
• syntax_node_to_token_tree
  Converts a syntax tree to a [tt::Subtree] using the provided span map to populate the subtree’s spans.
• syntax_node_to_token_tree_modified
  Converts a syntax tree to a [tt::Subtree] using the provided span map to populate the subtree’s spans. Additionally using the append and remove parameters, the additional tokens can be injected or hidden from the output.
• to_parser_input
• token_tree_to_syntax_node
  Converts a [tt::Subtree] back to a [SyntaxNode]. The produced SpanMap contains a mapping from the syntax nodes offsets to the subtree’s spans.
