Deserializing JSON strings into borrowed &'a str fails at runtime on any escape sequence, requiring Cow<'a, str> with #[serde(borrow)] to achieve zero-copy deserialization that safely falls back to allocation for escaped characters

Contract

• assert serde_json from_str borrows unescaped JSON string fields directly into &'a str with zero allocation
• assert serde_json from_str rejects &'a str deserialization on escape sequences like \n, \", \t, and \uXXXX with invalid type error
• assert serde_json from_str with #[serde(borrow)] Cow<'a, str> borrows unescaped strings as Cow::Borrowed and decodes escaped strings into Cow::Owned
• assert serde_json from_str with unannotated Cow<'a, str> defaults to DeserializeOwned and unconditionally allocates Cow::Owned
• assert serde_json from_slice matches from_str zero-copy borrowing behavior for &'a str and Cow<'a, str>
