Struct Unary 

pub struct Unary {
    pub operator: Operator,
    pub expr: ExprRef,
}

Unary operation (e.g., -x, NOT active).

Represents operations that take a single operand.

Examples

In WHERE NOT e.deleted, the NOT e.deleted is a unary operation.

Fields

operator: Operator

The operator (Add for +, Sub for -, Not for NOT)

expr: ExprRef

The operand expression

Trait Implementations

impl Clone for Unary

fn clone(&self) -> Unary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Unary

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

Formats the value using the given formatter.

impl Hash for Unary

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 PartialEq for Unary

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Unary

impl Eq for Unary

impl StructuralPartialEq for Unary
