Enum ConditionExpr 

pub enum ConditionExpr {
    Equals(ValueExpr, ValueExpr),
    And(Vec<ConditionExpr>),
    Or(Vec<ConditionExpr>),
    Not(Box<ConditionExpr>),
    ConditionRef(String),
    Invalid,
}

Variants

Equals(ValueExpr, ValueExpr)

And(Vec<ConditionExpr>)

Or(Vec<ConditionExpr>)

Not(Box<ConditionExpr>)

ConditionRef(String)

Invalid

A condition body that does not produce a boolean (e.g. a bare Fn::Ref, a scalar, or a value-producing function). CloudFormation rejects it; it is reported as a not-a-boolean error and is deliberately opaque to the SAT model and to the undefined-reference check (it is not a condition reference).
