Struct AeronLossReporter 

pub struct AeronLossReporter { /* private fields */ }

Implementations

impl AeronLossReporter

pub fn new( buffer: *mut u8, next_record_offset: usize, capacity: usize, ) -> 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 buffer(&self) -> *mut u8

pub fn next_record_offset(&self) -> usize

pub fn capacity(&self) -> usize

pub fn init(&self, buffer: &mut [u8]) -> Result<i32, AeronCError>

pub fn create_entry( &self, initial_bytes_lost: i64, timestamp_ms: i64, session_id: i32, stream_id: i32, channel: &str, source: &str, ) -> aeron_loss_reporter_entry_offset_t

pub fn record_observation( &self, offset: aeron_loss_reporter_entry_offset_t, bytes_lost: i64, timestamp_ms: i64, )

pub fn resolve_filename( directory: &CStr, filename_buffer: &mut [u8], ) -> Result<i32, AeronCError>

pub fn read<AeronLossReporterReadEntryFuncHandlerImpl: AeronLossReporterReadEntryFuncCallback>( buffer: &[u8], entry_func: Option<&Handler<AeronLossReporterReadEntryFuncHandlerImpl>>, ) -> usize

pub fn read_fn<AeronLossReporterReadEntryFuncHandlerImpl: FnMut(i64, i64, i64, i64, i32, i32, &str, &str)>( buffer: &[u8], entry_func: AeronLossReporterReadEntryFuncHandlerImpl, ) -> usize

Stack-borrowed closure (_fn variant): the FnMut closure lives on the caller’s stack and is borrowed for this call only — the callback fires synchronously inside the call, so nothing is heap-allocated, nothing is stored, and the closure may borrow local state. Prefer this over the retained Handler-based form on the hot path; only generated for callbacks the C client does not retain (i.e. not stored for later firing).

Panics

A panic inside the closure cannot unwind across the extern "C" callback boundary and aborts the process (since Rust 1.81). Return early instead of panicking in production fragment handlers.

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

pub unsafe fn get_inner_mut(&self) -> &mut aeron_loss_reporter_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_loss_reporter_t

impl AeronLossReporter

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)
