Struct WriteEntry 

pub struct WriteEntry {
    pub timestamp: i64,
    pub metric_name: String,
    pub value: f64,
    pub tags: HashMap<String, String>,
}

A time-series write entry that is replicated through the Raft log.

This is the high-level application-facing write primitive; it is internally converted to a TsdbCommand::WriteDatapoint before being proposed to the Raft log.

Fields

timestamp: i64

Unix epoch milliseconds.

metric_name: String

Metric / series name.

value: f64

Observed measurement value.

tags: HashMap<String, String>

Optional tag key-value pairs for dimensionality.

Implementations

impl WriteEntry

pub fn new(timestamp: i64, metric_name: impl Into<String>, value: f64) -> Self

Create a new write entry with no tags.

pub fn with_tag(self, key: impl Into<String>, value: impl Into<String>) -> Self

Builder: add a single tag.

pub fn with_tags(self, tags: HashMap<String, String>) -> Self

Builder: add multiple tags at once.

pub fn to_command(&self) -> TsdbCommand

Convert to a TsdbCommand::WriteDatapoint for Raft replication.

Trait Implementations

impl Clone for WriteEntry

fn clone(&self) -> WriteEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WriteEntry

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

Formats the value using the given formatter.

impl PartialEq for WriteEntry

fn eq(&self, other: &WriteEntry) -> 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.
