pub struct AeronSubscribable { /* private fields */ }

Implementations

impl AeronSubscribable

pub fn new( correlation_id: i64, length: usize, capacity: usize, array: &AeronTetherablePosition, inactive_count: usize, add_position_hook_func: Option<unsafe extern "C" fn(clientd: *mut c_void, value_addr: *mut i64)>, remove_position_hook_func: Option<unsafe extern "C" fn(clientd: *mut c_void, value_addr: *mut i64)>, clientd: *mut c_void, ) -> Result<Self, AeronCError>

pub fn new_zeroed_on_heap() -> Self

creates zeroed struct where the underlying c struct is on the heap

pub fn new_zeroed_on_stack() -> Self

creates zeroed struct where the underlying c struct is on the stack (Use with care)

pub fn correlation_id(&self) -> i64

pub fn length(&self) -> usize

pub fn capacity(&self) -> usize

pub fn array(&self) -> AeronTetherablePosition

pub fn inactive_count(&self) -> usize

pub fn add_position_hook_func( &self, ) -> Option<unsafe extern "C" fn(clientd: *mut c_void, value_addr: *mut i64)>

pub fn remove_position_hook_func( &self, ) -> Option<unsafe extern "C" fn(clientd: *mut c_void, value_addr: *mut i64)>

pub fn clientd(&self) -> *mut c_void

pub fn aeron_driver_subscribable_state( &self, tetherable_position: &AeronTetherablePosition, state: aeron_subscription_tether_state_t, now_ns: i64, stream_id: i32, session_id: i32, log_func: aeron_untethered_subscription_state_change_func_t, )

pub fn aeron_driver_subscribable_working_position_count(&self) -> usize

pub fn aeron_driver_subscribable_has_working_positions(&self) -> bool

pub fn aeron_driver_subscribable_remove_position(&self, counter_id: i32)

pub fn get_inner(&self) -> *mut aeron_subscribable_t

pub unsafe fn get_inner_mut(&self) -> &mut aeron_subscribable_t

Mutable access to the underlying C struct, minted from &self: nothing prevents two live &mut at once, so the caller must ensure exclusive access for the lifetime of the returned reference.

Safety

No other reference (& or &mut) to the underlying struct may be alive while the returned &mut is in use.

pub fn get_inner_ref(&self) -> &aeron_subscribable_t

impl AeronSubscribable

pub fn clone_struct(&self) -> Self

Regular clone just increases the reference count of underlying count. clone_struct shallow copies the content of the underlying struct on heap.

NOTE: if the struct has references to other structs these will not be copied

Must be only used on structs which has no init/clean up methods. So its dangerous to use with Aeron/AeronContext/AeronPublication/AeronSubscription More intended for AeronArchiveRecordingDescriptor (note strings will not work as its a shallow copy)

Trait Implementations
