Module ra_ap_syntax::ast

Expand description

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.
edit_in_place
Structural editing for ast.
make
This module contains free-standing functions for creating AST fragments out of smaller pieces.
prec
Precedence representation.

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
HasAttrs
HasDocComments
HasGenericParams
HasLoopBody
HasModuleItem
HasName
HasTypeBounds
HasVisibility
IsString
RangeItem
Trait to describe operations common to both RangeExpr and RangePat.
