Fields

queue: String

by_state: HashMap<String, u64>

arrival_rate: f64

jobs/sec, 1m window

drain_rate: f64

jobs/sec, 1m window

time_to_drain_ms: i64

-1 when arrival >= drain: the alert condition

paused: bool

count_is_approximate: bool

bounded live-control contract true when a bound was hit

oldest_available_ms: i64

-1 when no job is currently available

quiet_groups: Option<QuietGroupMetrics>

weight: u32

queue-selection weight; unrelated to Envelope.weight

unfinished_jobs: u64

exact producer-depth counter, never approximate

max_unfinished_jobs: Option<u64>

absent = enqueue backpressure disabled

Implementations

impl QueueStats

pub fn max_unfinished_jobs(&self) -> u64

Returns the value of max_unfinished_jobs, or the default value if max_unfinished_jobs is unset.

Trait Implementations

impl Clone for QueueStats

fn clone(&self) -> QueueStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueueStats

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

Formats the value using the given formatter.

impl Default for QueueStats

fn default() -> Self

Returns the “default value” for a type.

impl Message for QueueStats

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 QueueStats

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

Equality operator ==.

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

Inequality operator !=.
