Charlie Marsh f16e780e0a Add an implicit concatenation flag to string and bytes constants (#6512) ... ## Summary Per the discussion in https://github.com/astral-sh/ruff/discussions/6183, this PR adds an `implicit_concatenated` flag to the string and bytes constant variants. It's not actually _used_ anywhere as of this PR, but it is covered by the tests. Specifically, we now use a struct for the string and bytes cases, along with the `Expr::FString` node. That struct holds the value, plus the flag: ```rust #[derive(Clone, Debug, PartialEq, is_macro::Is)] pub enum Constant { Str(StringConstant), Bytes(BytesConstant), ... } #[derive(Clone, Debug, PartialEq, Eq)] pub struct StringConstant { /// The string value as resolved by the parser (i.e., without quotes, or escape sequences, or /// implicit concatenations). pub value: String, /// Whether the string contains multiple string tokens that were implicitly concatenated. pub implicit_concatenated: bool, } impl Deref for StringConstant { type Target = str; fn deref(&self) -> &Self::Target { self.value.as_str() } } #[derive(Clone, Debug, PartialEq, Eq)] pub struct BytesConstant { /// The bytes value as resolved by the parser (i.e., without quotes, or escape sequences, or /// implicit concatenations). pub value: Vec<u8>, /// Whether the string contains multiple string tokens that were implicitly concatenated. pub implicit_concatenated: bool, } impl Deref for BytesConstant { type Target = [u8]; fn deref(&self) -> &Self::Target { self.value.as_slice() } } ``` ## Test Plan `cargo test`		2023-08-14 13:46:54 +00:00
