|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1238: Macro queries r=edwin0cheng a=matklad In https://github.com/rust-analyzer/rust-analyzer/pull/1231, I've added aggressive clean up of `ast_id_to_node` query. The result of this query is a `SyntaxTree`, and we don't want to retain syntax trees in memory unless absolutely necessary. Moreover, `SyntaxTree` has identity equality semantics, meaning that we'll get a diffferent syntax tree for a file after every reparse. That means that `ast_id_to_node` query should not genereally be used in HIR, unless it is behind some kind of salsa firewall, like the `raw` module of name resoulution. However, that PR resulted in the abysmal performance: turns out we were using ast_id_to_node quite heavily in hir when expanding macros! So this PR installs the more incremental-friendly query structure: * converting source to token tree is now a query; changing source without affecting token-trees will now preserve macro expansions * expand macro (tt -> tt) is now a query as well, so we cache macro expansions *before* parsing them into item lists or expressions, which is nice: we can cache expansion without knowing the calling context! r? @edwin0cheng Co-authored-by: Aleksey Kladov <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | Currently, when expanding macros, we look at the source code directly (we invoke ast_id_to_node query via to_node method). This is less then ideal, because it make us re-expand macros after every source change. This commit establishes a salsa-firewall: a query to get macro call's token tree. Unlike the syntax tree, token tree changes only if we actually modify the macro itself.
