Implementations

impl<'a> AncillaryData<'a>

unsafe fn as_rights(data: &'a [u8]) -> Self

Creates an AncillaryData::ScmRights variant.

Safety

data must contain a valid control message and the control message must be type of SOL_SOCKET and level of SCM_RIGHTS.

unsafe fn as_credentials(data: &'a [u8]) -> Self

Creates an AncillaryData::ScmCredentials variant.

Safety

data must contain a valid control message and the control message must be type of SOL_SOCKET and level of SCM_CREDENTIALS or SCM_CREDS.
