Struct EventKey 

pub struct EventKey { /* private fields */ }

One key: a point in time, a time range or a labelled interval, in epoch milliseconds, as pond-ts Time / TimeRange / Interval. Used to look rows up (TimeSeries::bisect and friends) and given by Row::key. A plain i64 converts to a point in time. (A series’ whole key column is a Key.)

Implementations

impl EventKey

pub fn time(at: i64) -> Self

A point in time.

pub fn time_range(begin: i64, end: i64) -> Result<Self>

A time range from begin to end. An error when begin > end, as in pond-ts.

pub fn interval(label: impl Into<Label>, begin: i64, end: i64) -> Result<Self>

An interval from begin to end, labelled label. An error when begin > end, as in pond-ts, or when a number label is not finite (pond-rs labels are finite; pond-ts does not check).

pub fn begin(&self) -> i64

The start, in epoch milliseconds.

pub fn end(&self) -> i64

The end, in epoch milliseconds (the start, for a point in time).

pub fn label(&self) -> Option<&Label>

The label of an interval; None for other kinds.

pub fn kind(&self) -> &'static str

"time", "timeRange" or "interval", as pond-ts type().
