Module std::ptr

Unsafe pointer utility functions

Traits

Extension methods for raw pointers.

array_each	Given a null-pointer-terminated *T (pointer to an array of pointers), iterate through each T, passing to the provided callback function
array_each_with_len	Given a *T (pointer to an array of pointers), iterate through each T, up to the provided `len`, passing to the provided callback function
buf_len	Return the offset of the first null pointer in `buf`.
copy_memory	Copies data from one location to another.
copy_nonoverlapping_memory	Copies data from one location to another.
mut_null	Create an unsafe mutable null pointer
null	Create an unsafe null pointer
position	Return the first offset `i` such that `f(buf[i]) == true`.
read	Reads the value from `*src` and returns it.
read_and_zero	Reads the value from `*src` and nulls it out. This currently prevents destructors from executing.
replace	Replace the value at a mutable location with a new one, returning the old value, without deinitialising either.
set_memory	Invokes memset on the specified pointer, setting `count * size_of::<T>()` bytes of memory starting at `dst` to `c`.
swap	Swap the values at two mutable locations of the same type, without deinitialising either. They may overlap.
zero_memory	Zeroes out `count * size_of::<T>` bytes of memory at `dst`
