Struct Stats

pub struct Stats {
    pub created_at: Option<Timestamp>,
    pub dropped_at: Option<Timestamp>,
    pub wakes: u64,
    pub waker_clones: u64,
    pub waker_drops: u64,
    pub last_wake: Option<Timestamp>,
    pub poll_stats: Option<PollStats>,
    pub self_wakes: u64,
    pub scheduled_time: Option<Duration>,
}

Task performance statistics.

Fields

created_at: Option<Timestamp>

Timestamp of when the task was spawned.

dropped_at: Option<Timestamp>

Timestamp of when the task was dropped.

wakes: u64

The total number of times this task has been woken over its lifetime.

waker_clones: u64

The total number of times this task’s waker has been cloned.

waker_drops: u64

The total number of times this task’s waker has been dropped.

last_wake: Option<Timestamp>

The timestamp of the most recent time this task has been woken.

If this is None, the task has not yet been woken.

poll_stats: Option<PollStats>

Contains task poll statistics.

self_wakes: u64

The total number of times this task has woken itself.

scheduled_time: Option<Duration>

The total duration this task was scheduled prior to being polled, summed across all poll cycles.

Note that this includes only polls that have started, and does not reflect any scheduled state where the task hasn’t yet been polled. Subtracting both busy_time (from the task’s PollStats) and scheduled_time from the total lifetime of the task results in the amount of time it spent unable to progress because it was waiting on some resource.

Trait Implementations

impl Clone for Stats

fn clone(&self) -> Stats

Returns a copy 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.

impl Default for Stats

fn default() -> Self

Returns the “default value” for a type.

impl Message for Stats

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Stats

fn eq(&self, other: &Stats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Stats

impl StructuralPartialEq for Stats
