Module: Carbon::Core::Pointer::Cast Private

Included in:
Carbon::Core::Pointer
Defined in:
lib/carbon/core/pointer/cast.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

Performs casting for pointers. This converts them into an integer for use in the program. This defines the following functions on the pointer type:

  • .to-int64(self): Carbon::Int64
  • .to-uint64(self): Carbon::UInt64
  • .to-int32(self): Carbon::Int32
  • .to-uint32(self): Carbon::UInt32
  • .to-int16(self): Carbon::Int16
  • .to-uint16(self): Carbon::UInt16
  • .to-int8(self): Carbon::Int8
  • .to-uint8(self): Carbon::UInt8
