Struct AeronDeque

pub struct AeronDeque { /* private fields */ }

Implementations

impl AeronDeque

pub fn new( data: *mut u8, element_count: usize, element_size: usize, first_element: usize, last_element: usize, ) -> Result<Self, AeronCError>

pub fn new_zeroed() -> Result<Self, AeronCError>

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

pub fn data(&self) -> *mut u8

pub fn element_count(&self) -> usize

pub fn element_size(&self) -> usize

pub fn first_element(&self) -> usize

pub fn last_element(&self) -> usize

pub fn init( &self, initial_element_count: usize, element_size: usize, ) -> Result<i32, AeronCError>

pub fn close(&self)

pub fn add_last(&self, value: *mut c_void) -> Result<i32, AeronCError>

Add value into the deque as the last element. Will memcpy into the deque from the void pointer provided using the specified element size. May need to allocate in order to increase the size of the dequeue.

Errors: ENOMEM if growing the array fails.

Parameters

• deque to add the value too.

• value value to be added.

Return

0 on success, -1 on failure.

pub fn remove_first(&self, value: *mut c_void) -> Result<i32, AeronCError>

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

impl AeronDeque

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 danagerous to use with Aeron/AeronContext/AeronPublication/AeronSubscription More intended for AeronArchiveRecordingDescriptor

Trait Implementations

impl Clone for AeronDeque

fn clone(&self) -> AeronDeque

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AeronDeque

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

Formats the value using the given formatter.

impl Default for AeronDeque

This will create an instance where the struct is zeroed, use with care

fn default() -> Self

Returns the “default value” for a type.

impl Deref for AeronDeque

type Target = aeron_deque_stct

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
