Struct IoCounts 

#[non_exhaustive]
pub struct IoCounts {
    pub reads: u64,
    pub writes: u64,
    pub bytes_read: u64,
    pub bytes_written: u64,
    pub accepts: u64,
}

The IO operations a shard’s thread completed: see ShardStats::io. With the io-stats feature only.

An operation is counted when the kernel completes it: a read or receive that returned bytes or the end of the stream, a write or send that took bytes, a connection accepted. A read served from the read-ahead is counted when the read-ahead’s own read completed, and a write taken into the write-behind when the write-behind’s own write did. Peeks and readiness probes are not counted. IO completed on a thread that runs no shard (the blocking pool’s own calls, a thread outside the runtime) is counted by no shard.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

reads: u64

Reads and receives.

writes: u64

Writes and sends.

bytes_read: u64

Bytes the counted reads returned.

bytes_written: u64

Bytes the counted writes took.

accepts: u64

Connections accepted.
