Enum AddRuleError

#[non_exhaustive]
pub enum AddRuleError<T>
where
    T: Access,
{
    AddRuleCall {
        source: Error,
    },
    UnhandledAccess {
        access: BitFlags<T>,
        incompatible: BitFlags<T>,
    },
    Compat(CompatError<T>),
}

Identifies errors when adding a rule to a ruleset.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AddRuleCall

The landlock_add_rule() system call failed.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: Error

UnhandledAccess

The rule’s access-rights are not all handled by the (requested) ruleset access-rights.

Fields

access: BitFlags<T>

incompatible: BitFlags<T>

Compat(CompatError<T>)

Trait Implementations

impl<T> Debug for AddRuleError<T>

where T: Access + Debug,

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

Formats the value using the given formatter.

impl<T> Display for AddRuleError<T>

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

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

Formats the value using the given formatter.

impl<T> Error for AddRuleError<T>

where T: Access, CompatError<T>: Error, Self: Debug + Display,

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

Returns 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<A> From<AddRuleError<A>> for AddRulesError

where A: Access,

fn from(error: AddRuleError<A>) -> Self

Converts to this type from the input type.

impl<T> From<CompatError<T>> for AddRuleError<T>

where T: Access,

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

Converts to this type from the input type.
