Function std::ptr::read [] [src]

pub unsafe fn read<T>(src: *const T) -> T

Reads the value from src`srcwithout moving it. This leaves the memory insrc` unchanged.

Safety

Beyond accepting a raw pointer, this is unsafe because it semantically moves the value out of src`srcwithout preventing further usage ofsrc. If`. If T`Tis not` is not Copy`Copy, then care must be taken to ensure that the value atsrcis not used before the data is overwritten again (e.g. withwrite,`, zero_memory, or copy_memory). Note that *src = foo counts as a use because it will attempt to drop the value previously at *src`*src`.
