A field filter operator.

Variants

Unspecified = 0

Unspecified. This value must not be used.

LessThan = 1

The given field is less than the given value.

Requires:

• That field come first in order_by.

LessThanOrEqual = 2

The given field is less than or equal to the given value.

Requires:

• That field come first in order_by.

GreaterThan = 3

The given field is greater than the given value.

Requires:

• That field come first in order_by.

GreaterThanOrEqual = 4

The given field is greater than or equal to the given value.

Requires:

• That field come first in order_by.

Equal = 5

The given field is equal to the given value.

NotEqual = 6

The given field is not equal to the given value.

Requires:

• No other NOT_EQUAL, NOT_IN, IS_NOT_NULL, or IS_NOT_NAN.
• That field comes first in the order_by.

ArrayContains = 7

The given field is an array that contains the given value.

In = 8

The given field is equal to at least one value in the given array.

Requires:

• That value is a non-empty ArrayValue, subject to disjunction limits.
• No NOT_IN filters in the same query.

ArrayContainsAny = 9

The given field is an array that contains any of the values in the given array.

Requires:

• That value is a non-empty ArrayValue, subject to disjunction limits.
• No other ARRAY_CONTAINS_ANY filters within the same disjunction.
• No NOT_IN filters in the same query.

NotIn = 10

The value of the field is not in the given array.

Requires:

• That value is a non-empty ArrayValue with at most 10 values.
• No other OR, IN, ARRAY_CONTAINS_ANY, NOT_IN, NOT_EQUAL, IS_NOT_NULL, or IS_NOT_NAN.
• That field comes first in the order_by.

Implementations

impl Operator

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Operator.

pub fn from_i32(value: i32) -> Option<Operator>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a Operator, or None if value is not a valid variant.

impl Operator

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for Operator

fn clone(&self) -> Operator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Operator

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

Formats the value using the given formatter.

impl Default for Operator

fn default() -> Operator

Returns the “default value” for a type.

impl From<Operator> for i32

fn from(value: Operator) -> i32

Converts to this type from the input type.

impl Hash for Operator

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Operator

fn cmp(&self, other: &Operator) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Operator

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

impl PartialOrd for Operator

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<i32> for Operator

type Error = DecodeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Operator, DecodeError>

Performs the conversion.

impl Copy for Operator

impl Eq for Operator

impl StructuralPartialEq for Operator
