Enum MDQueryConditionExpression 

pub enum MDQueryConditionExpression {
    Condition(MDQueryCondition),
    Expression(String),
}

Represents either a nested condition or a raw query expression string.

This enum allows for building complex, nested query structures by combining both raw expression strings and other condition structures.

Variants

Condition(MDQueryCondition)

A nested condition structure

Expression(String)

A raw query expression string

Implementations

impl MDQueryConditionExpression

pub fn into_expression(self) -> String

Converts the expression into a query string.

For nested conditions, this recursively processes the condition structure. For raw expressions, it wraps the expression in parentheses.

Returns

A properly formatted query string representation of this expression.
