[−][src]Struct syn::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.
This type is available 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>)>
