Enum LandlockStatus 

pub enum LandlockStatus {
    NotEnabled,
    NotImplemented,
    Available {
        effective_abi: ABI,
        kernel_abi: Option<i32>,
    },
}

Status of Landlock support for the running system.

This enum is used to represent the status of the Landlock support for the system where the code is executed. It can indicate whether Landlock is available or not.

Warning

Sandboxed programs should only use this data to log or provide information to users, not to change their behavior according to this status. Indeed, the Ruleset and the other types are designed to handle the compatibility in a simple and safe way.

Variants

NotEnabled

Landlock is supported but not enabled (EOPNOTSUPP).

NotImplemented

Landlock is not implemented (i.e. not built into the running kernel: ENOSYS).

Available

Landlock is available and working on the running system.

This indicates that the kernel supports Landlock and it’s properly enabled. The crate uses the effective_abi for all operations, which represents the highest ABI version that both the kernel and this crate understand.

Fields

effective_abi: ABI

The effective ABI version that this crate will use for Landlock operations. This is the intersection of what the kernel supports and what this crate knows about.

kernel_abi: Option<i32>

The actual kernel ABI version when it’s newer than any ABI supported by this crate.

If Some(version), it means the running kernel supports Landlock ABI version which is higher than the latest ABI known by this crate.

This field is purely informational and is never used for Landlock operations. The crate always and only uses effective_abi for all functionality.

Trait Implementations

impl Clone for LandlockStatus

fn clone(&self) -> LandlockStatus

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LandlockStatus

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

Formats the value using the given formatter.

impl From<LandlockStatus> for ABI

fn from(status: LandlockStatus) -> Self

Converts to this type from the input type.

impl PartialEq for LandlockStatus

fn eq(&self, other: &LandlockStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
