Function pointer types for output sink plugins (alerts, webhooks, etc.)

Fields

init: Option<unsafe extern "C" fn(*const u8, usize) -> *mut c_void>

Initialize the output sink with configuration. config: MessagePack-encoded configuration object Returns: opaque instance pointer, or null on error

get_handled_tags: Option<unsafe extern "C" fn(*mut c_void, *mut *mut u8, *mut usize)>

Get the tags this sink handles (for routing). Returns a MessagePack-encoded array of strings. Empty array means sink handles all alerts.

send: Option<unsafe extern "C" fn(*mut c_void, *const u8, usize) -> i32>

Send an alert. alert: MessagePack-encoded Alert struct Returns: 0 on success, non-zero error code on failure

flush: Option<unsafe extern "C" fn(*mut c_void) -> i32>

Flush any pending alerts. Returns: 0 on success, non-zero error code on failure

free_buffer: Option<unsafe extern "C" fn(*mut u8, usize)>

Free a buffer allocated by get_handled_tags.

drop: Option<unsafe extern "C" fn(*mut c_void)>

Cleanup and destroy the instance.
