Enum Key

Source

pub enum Key {
    Time(Vec<i64>),
    TimeRange(TimeRangeKeys),
    Interval(IntervalKeys),
}

Expand description

The key column.

Variants§

§

Time(Vec<i64>)

Points in time, epoch milliseconds, non-decreasing.

§

TimeRange(TimeRangeKeys)

Time ranges, ordered by begin, then end.

§

Interval(IntervalKeys)

Labelled intervals, ordered by begin, then end.

Implementations§

Source §

impl Key

Source

pub fn len(&self) -> usize

Number of values.

Source

pub fn is_empty(&self) -> bool

true when there are no rows.

Source

pub fn begin(&self) -> &[i64]

Start of each row (the time itself for point keys).

Source

pub fn end(&self) -> Option<&[i64]>

End of each row, or None for point keys.
