Esteban Küber a16722d221 Handle attempts to have multiple cfgd tail expressions ... When encountering code that seems like it might be trying to have multiple tail expressions depending on `cfg` information, suggest alternatives that will success to parse. ```rust fn foo() -> String { #[cfg(feature = "validation")] [1, 2, 3].iter().map(|c| c.to_string()).collect::<String>() #[cfg(not(feature = "validation"))] String::new() } ``` ``` error: expected `;`, found `#` --> $DIR/multiple-tail-expr-behind-cfg.rs:5:64 | LL | #[cfg(feature = "validation")] | ------------------------------ only `;` terminated statements or tail expressions are allowed after this attribute LL | [1, 2, 3].iter().map(|c| c.to_string()).collect::<String>() | ^ expected `;` here LL | #[cfg(not(feature = "validation"))] | - unexpected token | help: add `;` here | LL | [1, 2, 3].iter().map(|c| c.to_string()).collect::<String>(); | + help: alternatively, consider surrounding the expression with a block | LL | { [1, 2, 3].iter().map(|c| c.to_string()).collect::<String>() } | + + help: it seems like you are trying to provide different expressions depending on `cfg`, consider using `if cfg!(..)` | LL ~ if cfg!(feature = "validation") { LL ~ [1, 2, 3].iter().map(|c| c.to_string()).collect::<String>() LL ~ } else if cfg!(not(feature = "validation")) { LL ~ String::new() LL + } | ``` Fix #106020.		2023-11-16 21:21:26 +00:00
