Struct ExprIf

pub struct ExprIf {
    pub attrs: Vec<Attribute>,
    pub if_token: If,
    pub cond: Box<Expr>,
    pub then_branch: Block,
    pub else_branch: Option<(Else, Box<Expr>)>,
}

An if expression with an optional else block: if expr { ... } else { ... }.

The else branch expression may only be an If or Block expression, not any of the other types of expression.

Fields

attrs: Vec<Attribute>

if_token: If

cond: Box<Expr>

then_branch: Block

else_branch: Option<(Else, Box<Expr>)>
