UInt

struct UInt : UnsignedInteger, Comparable, Equatable

  • Creates an unsigned integer from PerlScalar. Throws if sv does not contain an unsigned integer.

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

  • Creates an unsigned integer from PerlScalar using Perl macros SvUV. Performs no additional checks.

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