Struct selinux::access_vector_cache::Fixed

pub struct Fixed<D = DenyAll, const SIZE: usize = DEFAULT_FIXED_SIZE> { /* private fields */ }

An access vector cache of fixed size and memory allocation. The underlying caching strategy is FIFO. Entries are evicted one at a time when entries are added to a full cache.

This implementation is thread-hostile; it expects all operations to be executed on the same thread.

Implementations

impl<D, const SIZE: usize> Fixed<D, SIZE>

pub fn new(delegate: D) -> Self

Constructs a fixed-size access vector cache that delegates to delegate.

Panics

This will panic when SIZE is 0; i.e., for any Fixed<D, 0>.

TODO: Eliminate dead_code guard.

Trait Implementations

impl<D, const SIZE: usize> ProxyMut<D> for Fixed<D, SIZE>

fn set_delegate(&mut self, delegate: D) -> D

impl<D: QueryMut, const SIZE: usize> QueryMut for Fixed<D, SIZE>

fn query( &mut self, source_sid: SecurityId, target_sid: SecurityId, target_class: AbstractObjectClass ) -> AccessVector

Computes the [AccessVector] permitted to source_sid for accessing target_sid, an object of type target_class.

impl<D, const SIZE: usize> ResetMut for Fixed<D, SIZE>

fn reset(&mut self) -> bool

Removes all entries from this cache and any reset delegate caches encapsulated in this cache. Returns true only if the cache is still valid after reset.
