Struct IfChain 

pub struct IfChain<'d> {
    pub links: Vec<Statement<'d>>,
    pub thens: Vec<Statement<'d>>,
    pub otherwise: Option<Statement<'d>>,
}

The if / else if series a unique/unique0/priority qualifier on the first if applies to (§12.4.2: “the entire series of if-else-if conditions”): the condition and then-statement of each link, in source order, and the final else statement if there is one. A nested else if carries no qualifier of its own (the grammar has none); an else holding a qualified if of its own is the final else and a separate statement.

Fields

links: Vec<Statement<'d>>

The if statement of each link (its predicate is links[i] .conditions(): plain, &&&-chained, or pattern-matching, §12.6).

thens: Vec<Statement<'d>>

otherwise: Option<Statement<'d>>
