Struct AeronCounterMetadataDescriptor 

pub struct AeronCounterMetadataDescriptor { /* private fields */ }

Implementations

impl AeronCounterMetadataDescriptor

pub fn new( state: i32, type_id: i32, free_for_reuse_deadline_ms: i64, key: [u8; 112], label_length: i32, label: [u8; 380], ) -> 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 state(&self) -> i32

pub fn type_id(&self) -> i32

pub fn free_for_reuse_deadline_ms(&self) -> i64

pub fn key(&self) -> [u8; 112]

pub fn label_length(&self) -> i32

pub fn label(&self) -> [u8; 380]

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

pub unsafe fn get_inner_mut(&self) -> &mut aeron_counter_metadata_descriptor_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_counter_metadata_descriptor_t

impl AeronCounterMetadataDescriptor

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
