alloc_observe.Sink

1/// A delivery target holding a type-erased context pointer and a function2/// pointer that accepts an event by value and returns `void`. Delivery occurs3/// synchronously on the thread finishing an observed span, directly in the4/// caller execution path with no intermediate queue. Because events from5/// distinct threads can arrive concurrently, the callback implementation must6/// synchronize access to shared state. The sink provides no internal buffer,7/// capacity management, dropping strategy, or error reporting mechanism. The8/// caller must guarantee that the `Sink` struct storage itself, the callback9/// context, and the callback code remain stable and valid in memory until10/// session shutdown returns.11pub const Sink = struct {12    context: *anyopaque,13    record: *const fn (context: *anyopaque, event: Event) void,14};
