pub struct RulesetCreated { /* private fields */ }
Expand description

Ruleset created with Ruleset::create().

Implementations§

source§

impl RulesetCreated

source

pub fn restrict_self(self) -> Result<RestrictionStatus, RulesetError>

Attempts to restrict the calling thread with the ruleset according to the best-effort configuration (see RulesetCreated::set_compatibility() and CompatLevel::BestEffort). Call prctl(2) with the PR_SET_NO_NEW_PRIVS according to the ruleset configuration.

On error, returns a wrapped RestrictSelfError.

source

pub fn try_clone(&self) -> Result<Self>

Creates a new RulesetCreated instance by duplicating the underlying file descriptor. Rule modification will affect both RulesetCreated instances simultaneously.

On error, returns std::io::Error.

Trait Implementations§

source§

impl AsMut<RulesetCreated> for RulesetCreated

source§

fn as_mut(&mut self) -> &mut RulesetCreated

Converts this type into a mutable reference of the (usually inferred) input type.
source§

impl Compatible for &mut RulesetCreated

source§

fn set_compatibility(self, level: CompatLevel) -> Self

To enable a best-effort security approach, Landlock features that are not supported by the running system are silently ignored by default, which is a sane choice for most use cases. However, on some rare circumstances, developers may want to have some guarantees that their applications will not run if a certain level of sandboxing is not possible. If we really want to error out when not all our requested requirements are met, then we can configure it with set_compatibility(). Read more
source§

fn set_best_effort(self, best_effort: bool) -> Self
where Self: Sized,

👎Deprecated: Use set_compatibility() instead
