pub enum Visit {
Children,
Parent,
}
Expand description
Visit strategy after having visited an AST node.
Some AST nodes have children – in enum’s variants, in some fields as nested in Vec
, etc.
Those nodes can be visited depending on the strategy you chose.
The visitor will go deeper in the AST by visiting all the children, if any. If no children are
present or if having children doesn’t make sense for a specific part of the AST, this
strategy will be ignored.
The visitor won’t visit children nor siblings and will go up.
