Enum zvariant::Fd

source ·
pub enum Fd<'f> {
    Borrowed(BorrowedFd<'f>),
    Owned(OwnedFd),
}
Expand description

A file-descriptor type wrapper.

Since std::os::fd::BorrowedFd and std::os::fd::OwnedFd types do not implement Serialize and Deserialize. So we provide a wrapper for both that implements these traits.
