Enum JsonStr 

pub enum JsonStr<'de> {
    Borrowed(&'de str),
    BorrowedNoEsc(&'de str),
    Owned(String),
}

A parsed JSON string: either a zero-copy borrow or a heap-allocated value.

The BorrowedNoEsc variant is returned by Scanner::read_str when no escape sequences were present in the JSON input. This lets the serializer skip the find_escape scan entirely — the string is provably escape-free.

Variants

Borrowed(&'de str)

Zero-copy borrow from the input. No longer emitted by Scanner::read_str (use JsonStr::BorrowedNoEsc instead); kept for API compatibility. ToJson will run write_escaped_str on this variant.

BorrowedNoEsc(&'de str)

Zero-copy borrow whose content is provably escape-free (the scanner hit a closing " before any \\). The serializer can bypass the find_escape scan and write the bytes directly.

Owned(String)
