Struct `WStrUnits`

pub struct WStrUnits<'a> { pub(in ::sys::helpers::wstr) lpwstr: NonNull<u16>, pub(in ::sys::helpers::wstr) lifetime: PhantomData<&'a [u16]> }

A safe iterator over a LPWSTR (aka a pointer to a series of UTF-16 code units terminated by a NULL).

Fields

lpwstr: NonNull<u16>
lifetime: PhantomData<&'a [u16]>

Implementations

`impl WStrUnits<'_>`

unsafe fn new(lpwstr: *const u16) -> Option<Self>

Creates the iterator. Returns None if lpwstr is null.

SAFETY: lpwstr must point to a null-terminated wide string that lives at least as long as the lifetime of this struct.

fn peek(&self) -> Option<NonZero<u16>>

fn advance_while<P: FnMut(NonZero<u16>) -> bool>(&mut self, predicate: P) -> usize

Advance the iterator while predicate returns true. Returns the number of items it advanced by.
