Implementations

impl Filter

pub fn eq(field: &str, value: Value) -> Filter

Creates an equality filter.

pub fn ne(field: &str, value: Value) -> Filter

Creates a not-equal filter.

pub fn gt(field: &str, value: Value) -> Filter

Creates a greater-than filter.

pub fn lt(field: &str, value: Value) -> Filter

Creates a less-than filter.

pub fn ge(field: &str, value: Value) -> Filter

Creates a greater-than-or-equal filter.

pub fn le(field: &str, value: Value) -> Filter

Creates a less-than-or-equal filter.

pub fn in_list(field: &str, values: Vec<Value>) -> Filter

Creates an IN filter.

pub fn like(field: &str, pattern: &str) -> Filter

Creates a LIKE filter.

pub fn not_null(field: &str) -> Filter

Creates a NOT NULL filter.

pub fn is_null(field: &str) -> Filter

Creates an IS NULL filter.

pub fn and(self, other: Filter) -> Filter

Chain two filters with AND.

pub fn or(self, other: Filter) -> Filter

Chain two filters with OR.

pub fn not(self) -> Filter

Negate a filter with NOT.

pub fn matches(&self, values: &[(ColumnDef, Value)]) -> Result<bool, QueryError>

Checks if the given values match the filter.

Trait Implementations

impl CandidType for Filter

fn _ty() -> Type

fn id() -> TypeId

fn idl_serialize<__S>( &self, __serializer: __S, ) -> Result<(), <__S as Serializer>::Error>

where __S: Serializer,

fn ty() -> Type

impl Clone for Filter

fn clone(&self) -> Filter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Filter

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Filter

fn deserialize<__D>( __deserializer: __D, ) -> Result<Filter, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Filter

fn eq(&self, other: &Filter) -> 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 Serialize for Filter

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Filter

impl StructuralPartialEq for Filter
