Abstract Syntax Tree, layered on top of untyped SyntaxNodes

Modules§

  • edit
    This module contains functions for editing syntax trees. As the trees are immutable, all function here return a fresh copy of the tree, instead of doing an in-place modification.
  • make
    This module contains free-standing functions for creating AST fragments out of smaller pieces.
  • prec
    Precedence representation.

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.
  • AstToken
    Like AstNode, but wraps tokens rather than interior nodes.
  • HasArgList
  • HasLoopBody
  • HasName
  • HasTextName
  • IsString
