Structure used to communicate ByteEvents, such as TX and ACK timestamps.
Declared in <folly/io/async/observer/AsyncSocketObserverInterface.h>
struct ByteEvent;| Name | Description |
|---|---|
Type | Kind of byte event; values start from 0 to enable indexing in arrays. |
| Name | Description |
|---|---|
ackTimestampRequestedOnWrite | For WRITE events, returns if ACK timestamp requested. |
schedTimestampRequestedOnWrite | For WRITE events, returns if SCHED timestamp requested. |
txTimestampRequestedOnWrite | For WRITE events, returns if TX timestamp requested. |
| Name | Description |
|---|---|
maybeHardwareTs | Hardware timestamp for non-WRITE events. |
maybeRawBytesTriedToWrite | For WRITE events, the number of raw bytes we tried to write. |
maybeRawBytesWritten | For WRITE events, the number of raw bytes written to the socket. |
maybeSoftwareTs | Kernel software timestamp for non-WRITE events (CLOCK_REALTIME on Linux). |
maybeWriteFlags | For WRITE events, the additional WriteFlags passed. |
offset | Offset of the corresponding byte in the raw byte stream. |
ts | Socket timestamp, as recorded by the AsyncSocket implementation. |
type | Kind of this byte event. |
