Implementations§

impl Operator

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

For simple operators, returns the symbol directly. For complex operators (BETWEEN, EXISTS), returns the keyword.

pub fn needs_value(&self) -> bool

IS NULL, IS NOT NULL, EXISTS, NOT EXISTS don’t need values.

pub fn is_simple_binary(&self) -> bool

Trait Implementations§

impl Clone for Operator

fn clone(&self) -> Operator

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for Operator

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

Formats the value using the given formatter. Read more

impl<'de> Deserialize<'de> for Operator

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>
where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer. Read more

impl PartialEq for Operator

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

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

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 Operator

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
where S: Serializer,

Serialize this value into the given Serde serializer. Read more
