Struct syn::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.

This type is available only if Syn is built with the "full" feature.

Fields

attrs: Vec<Attribute>

if_token: If

cond: Box<Expr>

then_branch: Block

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