Enum Bound 

pub enum Bound {
    None,
    Date(Zoned),
    Timestamp(Zoned),
}

Possible variants of a CQL2 Instant and Interval limit.

Variants

None

Unbounded temporal value used as lower, upper, or both limit(s); represented by the string '..' .

Date(Zoned)

Instant with a 1-day granularity, in UTC time-zone.

Timestamp(Zoned)

Instant with a 1-second or less granularity in UTC time-zone.

Implementations

impl Bound

pub fn try_new_date(s: &str) -> Result<Self, MyError>

Try creating a new Bound::Date variant from a well-formed RFC-3339 date string. Return MyError if an error occurs.

pub fn try_new_timestamp(s: &str) -> Result<Self, MyError>

Try creating a new Bound::Timestamp variant from a well-formed RFC-3339 timestamp string. Return MyError if an error occurs.

pub fn as_zoned(&self) -> Option<Zoned>

Return the inner value in Some if this is not the unbound variant. Return None otherwise.
