Concrete methods

Matches literal sequence of literal constant value expressions and returns a sequence of values.

Usage:

inline def sum(args: Int*): Int = ${ sumExpr('args) }
def sumExpr(argsExpr: Expr[Seq[Int]])(using Quotes): Expr[Int] = argsExpr match
  case Varargs(Exprs(args)) => Expr(args.sum)
    // args: Seq[Int]

To directly get the value of all expressions in a sequence exprs: Seq[Expr[T]] consider using exprs.map(_.value)/exprs.map(_.valueOrError) instead.

Type parameters

T: the type of values being extracted from the expressions

Value parameters

exprs: the sequence of expressions to extract values from

Attributes

Returns: Some containing the sequence of extracted values if all expressions yield a value, or None if any expression cannot be converted
