Struct Line

pub struct Line { /* private fields */ }

A line in the Influx Line Protocol

Implementations

impl Line

pub fn new(measurement: impl Into<Measurement>) -> Self

Create a new line for a measurement

let line = Line::new("measurement");
assert_eq!(line.measurement(), &"measurement".into());

pub fn measurement(&self) -> &Measurement

Return the measurement

let line = Line::new("measurement");
assert_eq!(line.measurement(), &"measurement".into());

pub fn insert_field( &mut self, name: impl Into<FieldName>, value: impl Into<FieldValue>, )

Insert a field in the line

let mut line = Line::new("measurement");
line.insert_field("latitude", FieldValue::Float(55.383333));
line.insert_field("longitude", FieldValue::Float(10.383333));
assert_eq!(line.field("latitude"), Some(&55.383333.into()));
assert_eq!(line.field("longitude"), Some(&10.383333.into()));

pub fn field(&self, name: impl Into<FieldName>) -> Option<&FieldValue>

Return the value of a field

let mut line = Line::new("measurement");
line.insert_field("latitude", 55.383333);
line.insert_field("longitude", 10.383333);
assert_eq!(line.field("latitude"), Some(&55.383333.into()));
assert_eq!(line.field("longitude"), Some(&10.383333.into()));

pub fn insert_tag( &mut self, name: impl Into<TagName>, value: impl Into<TagValue>, )

Insert a tag in the line

let mut line = Line::new("measurement");
line.insert_tag("city", "Odense");
assert_eq!(line.tag("city"), Some(&"Odense".into()));

pub fn tag(&self, name: impl Into<TagName>) -> Option<&TagValue>

Return the value of a tag

let mut line = Line::new("measurement");
line.insert_tag("city", "Odense");
assert_eq!(line.tag("city"), Some(&"Odense".into()));

pub fn set_timestamp(&mut self, timestamp: DateTime<Utc>)

Set the line timestamp

let mut line = Line::new("measurement");
line.set_timestamp(Utc.ymd(2014, 7, 8).and_hms(9, 10, 11));
assert_eq!(line.timestamp(), Some(&Utc.ymd(2014, 7, 8).and_hms(9, 10, 11)));

pub fn timestamp(&self) -> Option<&DateTime<Utc>>

Return the line timestamp

let mut line = Line::new("measurement");
line.set_timestamp(Utc.ymd(2014, 7, 8).and_hms(9, 10, 11));
assert_eq!(line.timestamp(), Some(&Utc.ymd(2014, 7, 8).and_hms(9, 10, 11)));

Trait Implementations

impl Clone for Line

fn clone(&self) -> Line

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Line

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

Formats the value using the given formatter.

impl Display for Line

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

Formats the value using the given formatter.

impl PartialEq for Line

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