Struct Stats 

#[non_exhaustive]
pub struct Stats {
    pub shards: Vec<ShardStats>,
    pub blocking_threads: usize,
    pub blocking_queue_depth: usize,
    pub off_shard_errors: ErrorCounts,
    pub receive_buffers_missing: u64,
}

A snapshot of the runtime’s counters: stats().

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.

shards: Vec<ShardStats>

Every shard alive: the workers first, by their place in their runtime, then the shards of threads that run block_on.

blocking_threads: usize

Threads of the blocking pools alive now, at work or idle.

blocking_queue_depth: usize

Jobs waiting in the blocking pools’ queues for a thread to take them.

off_shard_errors: ErrorCounts

Errors of IO run on threads that run no shard: a handle polled outside nuclei’s block_on and its tasks, or a completion delivered while its shard was not running.

receive_buffers_missing: u64

Shards that started without the io_uring receive buffers their configuration asked for, because the system had no memory for them (most often the locked-memory limit); their reads use the pool’s buffers instead.

Trait Implementations

impl Clone for Stats

fn clone(&self) -> Stats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Stats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
