Fields

subscription: *mut aeron_subscription_stct

The subscription to which this image belongs.

source_identity: *const i8

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.
