Detailed Description

Tracks extension types observed while parsing one TLS handshake message.

This structure is a compact bitmap used to detect duplicate extensions in a single TLS extension block. The TLS 1.3 extension grammar permits each extension type to appear at most once in a given message. The parser may reset this structure before parsing a message and call qsc_tls_extensions_bitmap_set() for each decoded extension type.
