Struct syn::ExprIf[−][src]

pub struct ExprIf { /* fields omitted */ }

Expand description

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.
