Struct ShmRingView 

pub struct ShmRingView { /* private fields */ }

Read-only attachment to one existing Orbit SHM ring.

Attaching never creates, initializes, resets, locks, or unlinks a segment. Dropping the view only unmaps this process’s local mapping. Use ShmRingView::lane to obtain a RingFrameSource for one physical lane.

Implementations

impl ShmRingView

pub fn attach_existing_with_policy( fleet_name: &str, kind: u8, policy: ShmAccessPolicy, ) -> Result<Self>

Attach read-only in the current user’s namespace with an explicit policy.

pub fn attach_existing(fleet_name: &str, kind: u8) -> Result<Self>

Attach to an existing ring owned by the effective user.

pub fn attach_existing_for_uid( fleet_name: &str, kind: u8, uid: u32, ) -> Result<Self>

Attach to an existing ring under an explicit uid-scoped name.

POSIX permissions still decide whether the calling process may open another user’s object.

pub fn attach_existing_for_uid_with_policy( fleet_name: &str, kind: u8, uid: u32, policy: ShmAccessPolicy, ) -> Result<Self>

Attach read-only after checking the named owner’s uid, selected gid and maximum permissions. OS access checks still apply to the calling process.

pub fn attach_typed<T: OrbitTyped>(fleet_name: &str) -> Result<Self>

Attach and also verify the caller’s typed ring contract.

pub fn metadata(&self) -> &ShmRingMetadata

pub fn current_version(&self) -> u64

Last semantic version allocated by the ring at observation time.

pub fn notification_generation(&self) -> u32

Current notification generation used by native readiness bridges.

pub fn lane(&self, lane: usize) -> Result<ShmRingLaneView<'_>>

Select one physical lane as a generic read-only frame source.

Trait Implementations

impl Debug for ShmRingView

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

Formats the value using the given formatter.
