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.

Trait Implementations

impl Clone for Bound

fn clone(&self) -> Bound

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bound

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

Formats the value using the given formatter.

impl Display for Bound

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

Formats the value using the given formatter.

impl From<Bound> for Q

fn from(value: Bound) -> Self

Converts to this type from the input type.

impl PartialEq for Bound

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

impl PartialOrd for Bound

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<&Q> for Bound

type Error = MyError

The type returned in the event of a conversion error.

fn try_from(value: &Q) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Q> for Bound

type Error = MyError

The type returned in the event of a conversion error.

fn try_from(value: Q) -> Result<Self, Self::Error>

Performs the conversion.
