Enum landlock::AccessError

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

}

Variants

Empty

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

Unknown

Fields

access: BitFlags<T>

unknown: BitFlags<T>

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

Incompatible

Fields

access: BitFlags<T>

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

PartiallyCompatible

Fields

access: BitFlags<T>

incompatible: BitFlags<T>

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

Trait Implementations

impl<T> Debug for AccessError<T>

where T: Access + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Display for AccessError<T>

where T: Access, BitFlags<T>: Debug,

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Error for AccessError<T>

where T: Access, Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl<T> From<AccessError<T>> for CompatError<T>

where T: Access,

fn from(source: AccessError<T>) -> Self

Converts to this type from the input type.
