Struct AeronDataHeader 

pub struct AeronDataHeader { /* private fields */ }

Implementations

impl AeronDataHeader

pub fn new( frame_header: AeronFrameHeader, term_offset: i32, session_id: i32, stream_id: i32, term_id: i32, reserved_value: i64, ) -> 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 frame_header(&self) -> AeronFrameHeader

pub fn term_offset(&self) -> i32

pub fn session_id(&self) -> i32

pub fn stream_id(&self) -> i32

pub fn term_id(&self) -> i32

pub fn reserved_value(&self) -> i64

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

pub unsafe fn get_inner_mut(&self) -> &mut aeron_data_header_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_data_header_t

impl AeronDataHeader

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

impl Clone for AeronDataHeader

fn clone(&self) -> AeronDataHeader

Returns a duplicate of the value.
