Module ezno_parser::visiting

Contains logic that makes viewing and transform parts of AST trivial through the visitor pattern

Structs

• Annex
• Chain
  Contains ChainVariables which signal the position in the AST
• VisitOptions
  Options for behavior when visiting AST. Customizable behavior is important for analysis
• Visitors
  A utility type which implements VisitorReceiver. Use for running a bunch of different immutable visitors over a immutable AST. Used for simple analysis
• VisitorsMut
  A utility type which implements VisitorMutReceiver. Use for running a bunch of different mutable visitors over a mutable AST. Therefore can remove, add or change AST

Enums

• BlockItem
  Wrapper type for StatementOrDeclaration. Needed because crate::Statement doesn’t come under StatementOrDeclaration in the case of crate::BlockOrSingleStatement
• BlockItemMut
  Wrapper type for StatementOrDeclaration. Needed because crate::Statement doesn’t come under StatementOrDeclaration in the case of crate::BlockOrSingleStatement
• ChainVariable
• ImmutableVariableOrProperty
• MutableVariableOrProperty

Traits

• SelfVisitable
  Yielded during visiting AST. Might not be 1:1 with AST and include a wrapping type
• SelfVisitableMut
  Yielded during visiting AST. Might not be 1:1 with AST and include a wrapping type
• Visitable
  For something to visitable it can visit all nested fields.
• Visitor
  A visitor over something which is hooked/is SelfVisitable with some generic Data
• VisitorMut
  A visitor over something which is hooked/is SelfVisitableMut with some Data
• VisitorMutReceiver
  These are a receiver traits of the visitor
• VisitorReceiver
  Something which has a bunch of callbacks for AST
