Multipart boundary parameter parsing: closing quotes exit quoted parameter state · case 02

Multipart boundary parameter parsing: closing quotes exit quoted parameter state.

Member previewVariant 2 · 3 implementations · 18 checks per implementation

Case contract

Parse a bounded Content-Type string with semicolon-separated parameters, quoted strings and backslash escapes inside quotes. Require multipart/byteranges (case-insensitive) and exactly one boundary parameter, with 1..12 ASCII printable characters excluding CR/LF. Other parameters ignored. Unbalanced quotes or dangling quoted escapes reject. Input x is the field string.

Why this case matters

Range responses combine representation identity, conditional requests, framing, and partial-object state.
