Module pomelo_parse::ast

Representation of the AST.

This follows rowan::ast. The basic idea is to try to “cast” the nodes of the concrete syntax tree (CST) to AST nodes based on their SyntaxKind. This is achieved with the AstNode and AstToken traits in this module.

Traits

AstNode

The main trait to go from untyped [SyntaxNode] to a typed AST. The conversion itself has zero runtime cost: AST and syntax nodes have exactly the same representation: a pointer to the tree root and a pointer to the node itself.
