Suggest adding quotation marks to identifiers in attributes When the user provides an identifier when a literal was expected in an attribute value, suggest adding quotation marks to the identifier to make it a string literal. For instance: ``` error: attribute value must be a literal --> $DIR/crate-type-non-crate.rs:9:16 | LL | #[crate_type = lib] | ^^^ help: try adding quotation marks: `"lib"` ```
