Enum Operation 

pub enum Operation {
    Eq(Operand),
    Lt(Operand),
    Lte(Operand),
    Gt(Operand),
    Gte(Operand),
    Contains(String),
    Exists,
}

The different types of operations supported by a Query.

Those operations apply to a given key, which is part of the enclosing Condition.

Variants

Eq(Operand)

Check if the value for the key is equal to this operand

Lt(Operand)

Check if the value for the key is less than this operand

Lte(Operand)

Check if the value for the key is less than or equal to this operand

Gt(Operand)

Check if the value for the key is greater than this operand

Gte(Operand)

Check if the value for the key is greater than or equal to this operand

Contains(String)

Check if the value for the key contains a certain sub-string

Exists

Check if the key exists

Trait Implementations

impl Clone for Operation

fn clone(&self) -> Operation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operation

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

Formats the value using the given formatter.

impl PartialEq for Operation

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