When collecting tokens there are two kinds of range: - a range relative to the parser's full token stream (which we get when we are parsing); - a range relative to a single AST node's token stream (which we use within `LazyAttrTokenStreamImpl` when replacing tokens). These are currently both represented with `Range` and it's easy to mix them up -- until now I hadn't properly understood the difference. This commit introduces `ParserRange` and `NodeRange` to distinguish them. This also requires splitting `ReplaceRange` in two, giving the new types `ParserReplacement` and `NodeReplacement`. (These latter two names reduce the overloading of the word "range".) The commit also rewrites some comments to be clearer. The end result is a little more verbose, but much clearer. --- compiler/rustc_builtin_macros/src/cfg_eval.rs | 2 +- compiler/rustc_parse/src/parser/attr.rs | 6 +- .../rustc_parse/src/parser/attr_wrapper.rs | 124 ++++++++++-------- compiler/rustc_parse/src/parser/mod.rs | 70 +++++++--- 4 files changed, 124 insertions(+), 78 deletions(-) diff --git a/compiler/rustc_builtin_macros/src/cfg_eval.rs b/compiler/rustc_builtin_macros/src/cfg_eval.rs index dc1874bfecbda..4b05c144d37d7 100644 --- a/compiler/rustc_builtin_macros/src/cfg_eval.rs +++ b/compiler/rustc_builtin_macros/src/cfg_eval.rs @@ -202,7 +202,7 @@ impl CfgEval<'_> { } // Now that we have our re-parsed `AttrTokenStream`, recursively configuring - // our attribute target will correctly the tokens as well. + // our attribute target will correctly configure the tokens as well. flat_map_annotatable(self, annotatable) } } diff --git a/compiler/rustc_parse/src/parser/attr.rs b/compiler/rustc_parse/src/parser/attr.rs index 12b9414d1f760..a98382efc3eba 100644 --- a/compiler/rustc_parse/src/parser/attr.rs +++ b/compiler/rustc_parse/src/parser/attr.rs @@ -8,7 +8,7 @@ use rustc_span::{sym, BytePos, Span};
