Variants

Eq

Like

Pattern match (LIKE with wildcards)

Implementations

impl FilterOp

pub fn parse(s: &str) -> (Self, &str)

Parse operator from string prefix.

pub fn valid_for(&self, field_type: FieldType) -> bool

Check if this operator is valid for the given field type.

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

Get SQL operator string.

Trait Implementations

impl Clone for FilterOp

fn clone(&self) -> FilterOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilterOp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FilterOp

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FilterOp

fn eq(&self, other: &FilterOp) -> 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 FilterOp

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
