Int

Creates a signed integer from PerlScalar. Throws if sv does not contain a signed integer.

let i = try Int(PerlScalar(100))                     // i == 100
let i = try Int(PerlScalar("100"))                   // i == 100
let i = try Int(PerlScalar(42.5))                    // i == 42
let i = try Int(PerlScalar())                        // throws
let i = try Int(PerlScalar(""))                      // throws
let i = try Int(PerlScalar("any"))                   // throws
let i = try Int(PerlScalar("50sec"))                 // throws
let i = try Int(PerlScalar("10000000000000000000"))  // throws
let i = try Int(PerlScalar("20000000000000000000"))  // throws
let i = try Int(PerlScalar("-10"))                   // i == -10
let i = try Int(PerlScalar("-20000000000000000000")) // throws

Creates a signed integer from PerlScalar using Perl macros SvIV. Performs no additional checks.

let i = Int(unchecked: PerlScalar(100))                       // i == 100
let i = Int(unchecked: PerlScalar("100"))                     // i == 100
let i = Int(unchecked: PerlScalar(42.5))                      // i == 42
let i = Int(unchecked: PerlScalar())                          // i == 0
let i = Int(unchecked: PerlScalar(""))                        // i == 0
let i = Int(unchecked: PerlScalar("any"))                     // i == 0
let i = Int(unchecked: PerlScalar("50sec"))                   // i == 50
let i = Int(unchecked: PerlScalar("10000000000000000000"))    // i == Int(bitPattern: 10000000000000000000)
let i = Int(unchecked: PerlScalar("20000000000000000000"))    // i == Int(bitPattern: UInt.max)
let i = Int(unchecked: PerlScalar("-10"))                     // i == -10
let i = Int(unchecked: PerlScalar("-20000000000000000000"))   // i == Int.min
