Function uninit_tools::cast_init_to_uninit_slice[−][src]

pub fn cast_init_to_uninit_slice<U>(init: &[U]) -> &[MaybeUninit<U>]ⓘNotable traits for &'_ mut [u8]
impl<'_> Write for &'_ mut [u8]impl<'_> Read for &'_ [u8]

Cast a slice of bytes into a slice of uninitialized bytes, pretending that it is uninitialized. This is completely safe, since MaybeUninit must have the exact same (direct) layout, like u8 has. The downside with this is that the information about initializedness is lost; unless relying on unsafe code, the resulting slice can only be used to prove validity of the memory range.
