Struct QuicInitial 

#[non_exhaustive]
pub struct QuicInitial {
    pub version: QuicVersion,
    pub dcid: Vec<u8>,
    pub scid: Vec<u8>,
    pub token_present: bool,
    pub sni: Option<String>,
    pub alpn: Vec<String>,
    pub client_hello: Option<TlsClientHello>,
}

Available on crate feature quic only.

One decoded QUIC Initial packet with its TLS ClientHello extracted.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

version: QuicVersion

QUIC version. Use QuicVersion::is_v1 / QuicVersion::is_v2 for routing.

dcid: Vec<u8>

scid: Vec<u8>

token_present: bool

true when a Retry token was attached.

sni: Option<String>

Server Name Indication extracted from the TLS ClientHello extension. None when the ClientHello was present but lacked an SNI extension.

alpn: Vec<String>

ALPN protocol identifiers from the TLS ClientHello extension (e.g. ["h3", "h3-29"]). Empty when the extension was absent.

client_hello: Option<TlsClientHello>

Available on crate feature tls only.

The full TLS ClientHello recovered from the Initial’s CRYPTO stream — present only when the tls feature is also enabled (issue #82). Carries the cipher / extension / version lists JA4 needs; feed it to crate::tls::ja4_quic or use the crate::quic::ja4 convenience. None when the CRYPTO stream held no parseable ClientHello.
