Module ast 

WS4 — the typed AST.

A thin, zero-cost typed view over the lossless CST (the rust-analyzer model). An AST node just wraps a red GdNode of the matching SyntaxKind; accessors are filtered child lookups. No data is copied. Because GdNode is a resolved node (it carries the interner), text accessors are clean — Name::text() needs no extra resolver argument.

Traits

AstNode

A typed node: a checked view over a red node of one SyntaxKind.

Functions
