PerlValue

open class PerlValue : AnyPerl, CustomDebugStringConvertible

Provides a safe wrapper for any SV, which can contain any Perl value, not only scalars. Performs reference counting on initialization and deinitialization.

  • Unsafely creates an instance without incrementing a reference counter of a SV. Performs no type checks and should be used only if compatibility is known.

    Declaration

  • Invokes the given closure on the unsafe context containing pointers to the SV and the Perl interpreter.

    The withUnsafeSvContext(_:) method ensures that the SV’s lifetime extends through the execution of body.

    Declaration

    Swift

    public final func withUnsafeSvContext<R>(_ body: (UnsafeSvContext) throws -> R) rethrows -> R

    Parameters

    body

    A closure that takes UnsafeSvContext as its argument. If the closure has a return value, it is used as the return value of the withUnsafeSvContext(_:) method.

    Return Value

    The return value of the body closure, if any.
