The type to temporarily bind the memory referenced by this buffer. The type
Tmust have the same size and be layout compatible with the pointer’s
A closure that takes a mutable typed buffer to the same memory as this buffer, only bound to type
T. The buffer argument contains the same number of complete instances of
Tas the original<br/>buffer’s
count. The closure’s buffer argument is valid only for the duration of the closure’s execution. If
bodyhas a return value, that value is also used as the return value for the
Memory Rebound(to: _:)
The return value, if any, of the
body closure parameter.
Use this method when you have a buffer of memory bound to one type and you need to access that memory as a buffer of another type. Accessing memory as type
T requires that the memory be bound to that type. A memory location may only be bound to one type at a time, so accessing the same memory as an unrelated type without first rebinding the memory is undefined.
The entire region of memory referenced by this buffer must be initialized.
Because this buffer’s memory is no longer bound to its
Element type while the
body closure executes, do not access memory using the original buffer from within
body. Instead, use the
body closure’s buffer argument to access the values in memory as instances of type
body, this method rebinds memory back to the original
