Enum regex_syntax::ast::visitor::ClassInduct
source · enum ClassInduct<'a> {
Item(&'a ClassSetItem),
BinaryOp(&'a ClassSetBinaryOp),
}
Expand description
A representation of the inductive step when performing structural induction over a character class.
Note that there is no analogous explicit type for the inductive step for
Ast
nodes because the inductive step is just an Ast
. For character
classes, the inductive step can produce one of two possible child nodes:
an item or a binary operation. (An item cannot be a binary operation
because that would imply binary operations can be unioned in the concrete
syntax, which is not possible.)
Variants§
Item(&'a ClassSetItem)
BinaryOp(&'a ClassSetBinaryOp)
