Struct Condition 

pub struct Condition {
    pub key: String,
    pub operation: Operation,
}

A condition which is part of a Query.

Fields

key: String

The key this condition applies to.

operation: Operation

The operation to apply to the key or its value, depending on the type of operation.

Implementations

impl Condition

pub fn new(key: String, operation: Operation) -> Self

Create a new condition that applies the given operation to the key

pub fn eq(key: String, op: Operand) -> Self

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

pub fn lt(key: String, op: Operand) -> Self

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

pub fn lte(key: String, op: Operand) -> Self

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

pub fn gt(key: String, op: Operand) -> Self

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

pub fn gte(key: String, op: Operand) -> Self

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

pub fn contains(key: String, op: String) -> Self

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

pub fn exists(key: String) -> Self

Check if the key exists

Trait Implementations

impl Clone for Condition

fn clone(&self) -> Condition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Condition

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

Formats the value using the given formatter.

impl Display for Condition

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

Formats the value using the given formatter.

impl PartialEq for Condition

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