Enum landlock::AccessError

pub enum AccessError<T>
where T: Access,
{ Empty, Unknown { access: BitFlags<T>, unknown: BitFlags<T>, }, Incompatible { access: BitFlags<T>, }, PartiallyCompatible { access: BitFlags<T>, incompatible: BitFlags<T>, }, }

Variants§

§

Empty

The access-rights set is empty, which doesn’t make sense and would be rejected by the kernel.

§

Unknown

The access-rights set was forged with the unsafe BitFlags::from_bits_unchecked() and it contains unknown bits.

Fields

§access: BitFlags<T>
§unknown: BitFlags<T>
§

Incompatible

The best-effort approach was (deliberately) disabled and the requested access-rights are fully incompatible with the running kernel.

Fields

§access: BitFlags<T>
§

PartiallyCompatible

The best-effort approach was (deliberately) disabled and the requested access-rights are partially incompatible with the running kernel.

Fields

§access: BitFlags<T>
§incompatible: BitFlags<T>
