Enum Condition 

#[non_exhaustive]
pub enum Condition {
    Comparison(Comparison),
    And(Box<Condition>, Box<Condition>),
    Or(Box<Condition>, Box<Condition>),
}

Boolean condition used in where clauses.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Comparison(Comparison)

단일 비교: field op value

And(Box<Condition>, Box<Condition>)

논리 AND: condition and condition

Or(Box<Condition>, Box<Condition>)

논리 OR: condition or condition

Trait Implementations

impl Clone for Condition

fn clone(&self) -> Condition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Condition

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

Formats the value using the given formatter.

impl PartialEq for Condition

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