Fields

channel: *const i8

Media address for delivery to the channel.

This returns a pointer only valid for the lifetime of the subscription.

on_available_image: Option<unsafe extern "C" fn(_: *mut c_void, _: *mut aeron_subscription_stct, _: *mut aeron_image_stct)>

Callback used to indicate when an Image becomes available under this Subscription.

on_unavailable_image: Option<unsafe extern "C" fn(_: *mut c_void, _: *mut aeron_subscription_stct, _: *mut aeron_image_stct)>

Callback used to indicate when an Image goes unavailable under this Subscription.

registration_id: i64

Return the registration id used to register this Subscription with the media driver.

stream_id: i32

Stream identity for scoping within the channel media address.

channel_status_indicator_id: i32

Counter id for the channel status indicator

impl PartialEq for aeron_subscription_constants_stct

fn eq(&self, other: &aeron_subscription_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.
