Struct const_iovec

#[repr(C)]
pub struct const_iovec {
    pub iov_base: *const c_void,
    pub iov_len: size_t,
}

Helper type to mark functions systemd functions that promise not to modify the underlying iovec data. There is no corresponding type in libc, so their function signatures take *const iovec, which technically allow iov_base to be modified. However, const_iovec provides the same ABI, so it can be used to make the function interface easier to work with.

Fields

iov_base: *const c_void

iov_len: size_t

Implementations

impl const_iovec

pub unsafe fn from_str<T>(arg: T) -> Self

where T: AsRef<str>,

Safety

Lifetime of arg must be long enough to cover future dereferences of the internal Self::iov_base pointer.
