pub struct Case {
    pub arg: Option<Box<Expr>>,
    pub whens: Vec<(Expr, Expr)>,
    pub default: Box<Expr>,
}

Fields

arg: Option<Box<Expr>>

The value that the conditions compare, for CASE x WHEN ....

whens: Vec<(Expr, Expr)>

Each condition with its result.

default: Box<Expr>

The result of ELSE, which is a null constant when the query has no ELSE.
