}

Configuration for an image that does not change during it’s lifetime.

Fields

subscription: *mut aeron_subscription_t

The subscription to which this image belongs.

source_identity: *const c_char

The source identity of the sending publisher as an abstract concept appropriate for the media.

correlation_id: i64

The correlationId for identification of the image with the media driver.

join_position: i64

Get the position the subscriber joined this stream at.

position_bits_to_shift: usize

Number of bits to right shift a position to get a term count for how far the stream has progressed.

term_buffer_length: usize

Get the length in bytes for each term partition in the log buffer.

mtu_length: usize

The length in bytes of the MTU (Maximum Transmission Unit) the Sender used for the datagram.

session_id: i32

The sessionId for the steam of messages. Sessions are unique within a subscription and unique across all publications from a source identity.

initial_term_id: i32

The initial term at which the stream started for this session.

subscriber_position_id: i32

Counter id that refers to the subscriber position for this image.

Trait Implementations

impl Clone for aeron_image_constants_stct

fn clone(&self) -> aeron_image_constants_stct

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for aeron_image_constants_stct

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

Formats the value using the given formatter.

impl Default for aeron_image_constants_stct

fn default() -> Self

Returns the “default value” for a type.

impl From<aeron_image_constants_stct> for AeronImageConstants

fn from(value: aeron_image_constants_t) -> Self

Converts to this type from the input type.

impl Hash for aeron_image_constants_stct

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for aeron_image_constants_stct

fn eq(&self, other: &aeron_image_constants_stct) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
