Struct `ExprIf`

struct ExprIf { ... }

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>)>
