Variants

Equals(Box<Expression<'a>>, Box<Expression<'a>>)

left = right

NotEquals(Box<Expression<'a>>, Box<Expression<'a>>)

left <> right

LessThan(Box<Expression<'a>>, Box<Expression<'a>>)

left < right

LessThanOrEquals(Box<Expression<'a>>, Box<Expression<'a>>)

left <= right

GreaterThan(Box<Expression<'a>>, Box<Expression<'a>>)

left > right

GreaterThanOrEquals(Box<Expression<'a>>, Box<Expression<'a>>)

left >= right

In(Box<Expression<'a>>, Box<Expression<'a>>)

left IN (..)

NotIn(Box<Expression<'a>>, Box<Expression<'a>>)

left NOT IN (..)

Like(Box<Expression<'a>>, Box<Expression<'a>>)

left LIKE %..%

NotLike(Box<Expression<'a>>, Box<Expression<'a>>)

left NOT LIKE %..%

Null(Box<Expression<'a>>)

value IS NULL

NotNull(Box<Expression<'a>>)

value IS NOT NULL

Between(Box<Expression<'a>>, Box<Expression<'a>>, Box<Expression<'a>>)

value BETWEEN left AND right

NotBetween(Box<Expression<'a>>, Box<Expression<'a>>, Box<Expression<'a>>)

value NOT BETWEEN left AND right

Raw(Box<Expression<'a>>, Cow<'a, str>, Box<Expression<'a>>)

Raw comparator, allows to use an operator left <raw> right as is, without visitor transformation in between.

JsonCompare(JsonCompare<'a>)

All json related comparators

Any(Box<Expression<'a>>)

ANY (left)

All(Box<Expression<'a>>)

ALL (left)

Trait Implementations

impl<'a> Clone for Compare<'a>

fn clone(&self) -> Compare<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Compare<'a>

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

Formats the value using the given formatter.

impl<'a> From<Compare<'a>> for ConditionTree<'a>

fn from(cmp: Compare<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<Compare<'a>> for Expression<'a>

fn from(cmp: Compare<'a>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq<Compare<'a>> for Compare<'a>

fn eq(&self, other: &Compare<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
