[TypeBindings, Tup] ( scrutineeExpr: Expr[Any] ) ( implicit  patternExpr: Expr[Any] hasTypeSplices: Boolean qctx: QuoteContext ) : Option[Tup]

Pattern matches an the scrutineeExpr against the patternExpr and returns a tuple with the matched holes if successful.

Examples: - Matcher.unapply('{ f(0...

[T]

Pattern matches an the scrutineeExpr against the patternExpr and returns a tuple with the matched holes if successful.

Examples: - Matcher.unapply('{ f(0, myInt) })('{ f(0, myInt) }, _) will return Some(()) (where () is a tuple of arity 0) - Matcher.unapply('{ f(0, myInt) })('{ f(patternHole[Int], patternHole[Int]) }, _) will return Some(Tuple2('{0}, '{ myInt })) - Matcher.unapply('{ f(0, "abc") })('{ f(0, patternHole[Int]) }, _) will return None due to the missmatch of types in the hole

Holes: - scala.internal.Quoted.patternHole[T]: hole that matches an expression x of type Expr[U] if U <:< T and returns x as part of the match.
