Struct console_api::PollStats

pub struct PollStats {
    pub polls: u64,
    pub first_poll: Option<Timestamp>,
    pub last_poll_started: Option<Timestamp>,
    pub last_poll_ended: Option<Timestamp>,
    pub busy_time: Option<Duration>,
}

Contains stats about objects that can be polled. Currently these can be:

• tasks that have been spawned
• async operations on resources that are performed within the context of a task

Fields

polls: u64

The total number of times this object has been polled.

first_poll: Option<Timestamp>

The timestamp of the first time this object was polled.

If this is None, the object has not yet been polled.

Subtracting this timestamp from created_at can be used to calculate the time to first poll for this object, a measurement of executor latency.

last_poll_started: Option<Timestamp>

The timestamp of the most recent time this objects’s poll method was invoked.

If this is None, the object has not yet been polled.

If the object has only been polled a single time, then this value may be equal to the first_poll timestamp.

last_poll_ended: Option<Timestamp>

The timestamp of the most recent time this objects’s poll method finished execution.

If this is None, the object has not yet been polled or is currently being polled.

If the object does not exist anymore, then this is the time the final invocation of its poll method has completed.

busy_time: Option<Duration>

The total duration this object was being actively polled, summed across all polls.

Note that this includes only polls that have completed, and does not reflect any in-progress polls. Subtracting busy_time from the total lifetime of the polled object results in the amount of time it has spent waiting to be polled (including the scheduled_time value from TaskStats, if this is a task).

Trait Implementations

impl Clone for PollStats

fn clone(&self) -> PollStats

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PollStats

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

Formats the value using the given formatter.

impl Default for PollStats

fn default() -> Self

Returns the “default value” for a type.

impl Message for PollStats

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

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

impl PartialEq for PollStats

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

This method tests for self and other values to be equal, and is used by ==.

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

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