Abstract methods
Pattern matches an the scrutineeExpr against the patternExpr and returns a tuple with the matched holes if successful.
Pattern matches an the scrutineeExpr against the patternExpr and returns a tuple with the matched holes if successful.
Examples:
ExprMatch.unapply('{ f(0, myInt) })('{ f(0, myInt) }, _)will returnSome(())(where()is a tuple of arity 0)ExprMatch.unapply('{ f(0, myInt) })('{ f(patternHole[Int], patternHole[Int]) }, _)will returnSome(Tuple2('{0}, '{ myInt }))ExprMatch.unapply('{ f(0, "abc") })('{ f(0, patternHole[Int]) }, _)will returnNonedue to the missmatch of types in the hole
Holes:
scala.quoted.runtime.Patterns.patternHole[T]: hole that matches an expression
xof typeExpr[U]ifU <:< Tand returnsxas part of the match.
