Detailed Description
An in-flight async operation that suspends a connection.
Three separate callbacks because deadline semantics differ per operation:
- Sleep: on_deadline = success (timer fired)
- HTTP: on_deadline = error (timeout)
- Gather: on_deadline = cancel remaining sub-ops, return partial results
Field Documentation
◆ conn
| KlConn* KlAsyncOp::conn |
Suspended connection
◆ deadline_ms
| uint64_t KlAsyncOp::deadline_ms |
Absolute deadline (0 = no deadline)
◆ on_resume
| KlAsyncFn KlAsyncOp::on_resume |
Called by kl_async_complete
◆ on_deadline
| KlAsyncFn KlAsyncOp::on_deadline |
Called when deadline_ms reached
◆ on_cancel
| KlAsyncFn KlAsyncOp::on_cancel |
Called if connection dies while suspended
◆ user_data
| void* KlAsyncOp::user_data |
Opaque (e.g. HlAsyncCtx*)
◆ next
| struct KlAsyncOp* KlAsyncOp::next |
Active ops list (server-owned)
