Trait PointerToCStr

pub(crate) trait PointerToCStr {
    // Required method
    unsafe fn to_lifetimed_cstr<'a>(self) -> Option<&'a CStr>;
}

Trait that eases conversions from a char pointer (no matter the signedness, they are used inconsistently in RIOT) to a CStr. The result is often used with ?.to_str().ok()?.

Required Methods

unsafe fn to_lifetimed_cstr<'a>(self) -> Option<&'a CStr>

Cast self around until it is suitable input to core::ffi::CStr::from_ptr(), and run that function. See there for safety requirements; in particular, the user needs to ensure that the lifetime is suitable.

This returns None if self is the null pointer.
