Struct Interval 

pub struct Interval {
    pub start_field: Option<(IntervalField, Span)>,
    pub end_field: Option<(IntervalField, Span)>,
    pub precision: Option<(usize, Span)>,
}

Interior of Type::Interval.

Fields

start_field: Option<(IntervalField, Span)>

The first (or only) field qualifier, e.g. YEAR in INTERVAL YEAR TO MONTH.

end_field: Option<(IntervalField, Span)>

The upper-bound field, e.g. MONTH in INTERVAL YEAR TO MONTH.

precision: Option<(usize, Span)>

Fractional-seconds precision; only meaningful when the rightmost unit is SECOND.
