Struct WriteMetrics 

pub struct WriteMetrics {
    pub count: u64,
    pub pending: Option<Microseconds>,
    pub rate: Option<f64>,
}

Metrics for writing to a topic (publication/producer).

Fields

count: u64

Number of messages successfully written.

pending: Option<Microseconds>

How long the producer has been waiting to write.

If set, indicates backpressure - the topic or downstream consumers are not keeping up.

rate: Option<f64>

Messages written per second (computed over a window).

Implementations

impl WriteMetrics

pub fn new(count: u64) -> WriteMetrics

Create new write metrics with a count.

pub fn builder() -> WriteMetricsBuilder

Create a builder for write metrics.

pub fn is_healthy(&self, max_pending: Microseconds) -> bool

Check if this write stream appears healthy.

Returns false if there’s a long pending time (backpressure).

Trait Implementations

impl Clone for WriteMetrics

fn clone(&self) -> WriteMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WriteMetrics

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

Formats the value using the given formatter.

impl Default for WriteMetrics

fn default() -> WriteMetrics

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WriteMetrics

fn deserialize<__D>( __deserializer: __D, ) -> Result<WriteMetrics, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WriteMetrics

fn eq(&self, other: &WriteMetrics) -> 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 Serialize for WriteMetrics

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
