Struct IpcCapability 

pub struct IpcCapability { /* private fields */ }

IPC capability structure

64-bit capability token format:

• Bits 63-48: Generation counter (for revocation)
• Bits 47-32: Capability type
• Bits 31-0: Unique ID

Implementations

impl IpcCapability

pub fn new(target: EndpointId, permissions: IpcPermissions) -> Self

Create a new capability

pub fn id(&self) -> u64

Get the capability ID

pub fn generation(&self) -> u16

Get the generation counter

pub fn cap_type(&self) -> CapabilityType

Get the capability type

pub fn target(&self) -> EndpointId

Get the target endpoint/process

pub fn owner(&self) -> ProcessId

Get the owner (same as target for compatibility)

pub fn has_permission(&self, perm: Permission) -> bool

Check if capability has specific permission

pub fn derive(&self, new_perms: IpcPermissions) -> Option<Self>

Derive a new capability with reduced permissions

pub fn revoke(&mut self)

Revoke this capability by incrementing generation

Trait Implementations

impl Clone for IpcCapability

fn clone(&self) -> IpcCapability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IpcCapability

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

Formats the value using the given formatter.

impl PartialEq for IpcCapability

fn eq(&self, other: &IpcCapability) -> 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.
