Struct TlsExtension 

pub struct TlsExtension<'a> { /* private fields */ }

A raw TLS extension preserving its type and opaque payload.

Implementations

impl<'a> TlsExtension<'a>

pub fn quic_transport_parameters( &self, ) -> Result<QuicTransportParameters<'a>, QuicTransportParametersTlsExtensionError>

Parses this RFC 9001 QUIC transport-parameters extension payload.

RFC 9001 permits this extension in ClientHello and EncryptedExtensions and requires it in both. Callers that own the parent handshake-message context enforce its placement and presence; this accessor parses only the extension payload.

impl<'a> TlsExtension<'a>

pub const fn extension_type(&self) -> TlsExtensionType

Returns the raw extension type.

pub const fn data(&self) -> &'a [u8]

Returns the exact extension payload.

pub fn client_server_name_list( &self, ) -> Result<ClientServerNameList<'a>, TlsParseError>

Parses the ClientHello server_name list layout.

pub fn server_name_acknowledgement(&self) -> Result<(), TlsParseError>

Validates the empty ServerHello server_name acknowledgement.

pub fn alpn_protocol_list(&self) -> Result<AlpnProtocolList<'a>, TlsParseError>

Parses an ordered ALPN protocol-name list.

pub fn server_selected_alpn( &self, ) -> Result<ServerSelectedAlpn<'a>, TlsParseError>

Parses the single protocol selected by a server ALPN extension.

pub fn client_supported_versions( &self, ) -> Result<ClientSupportedVersions<'a>, TlsParseError>

Parses the ClientHello supported_versions vector.

pub fn server_supported_version( &self, ) -> Result<TlsProtocolVersion, TlsParseError>

Returns the selected server or HelloRetryRequest protocol version.

pub fn server_supported_version_view( &self, ) -> Result<ServerSupportedVersion, TlsParseError>

Parses the server or HelloRetryRequest supported_versions layout.

pub fn supported_groups(&self) -> Result<SupportedGroups<'a>, TlsParseError>

Parses the ordered supported named groups.

pub fn signature_algorithms( &self, ) -> Result<SignatureAlgorithms<'a>, TlsParseError>

Parses the signature_algorithms scheme list.

pub fn signature_algorithms_cert( &self, ) -> Result<SignatureAlgorithms<'a>, TlsParseError>

Parses the signature_algorithms_cert scheme list.

pub fn ec_point_formats(&self) -> Result<EcPointFormats<'a>, TlsParseError>

Parses the legacy EC point-format list.

pub fn client_key_share(&self) -> Result<ClientKeyShare<'a>, TlsParseError>

Parses the ClientHello key-share entry vector.

pub fn server_key_share(&self) -> Result<ServerKeyShare<'a>, TlsParseError>

Parses the single ServerHello key-share entry.

pub fn hrr_key_share(&self) -> Result<HrrKeyShare, TlsParseError>

Parses the selected HelloRetryRequest key-share group.

pub fn psk_key_exchange_modes( &self, ) -> Result<PskKeyExchangeModes<'a>, TlsParseError>

Parses the ordered PSK key-exchange modes.

pub fn client_pre_shared_key( &self, ) -> Result<ClientPreSharedKey<'a>, TlsParseError>

Parses ClientHello PSK identities and binders.

pub fn server_pre_shared_key(&self) -> Result<ServerPreSharedKey, TlsParseError>

Parses the ServerHello selected PSK identity.

pub fn certificate_compression_algorithms( &self, ) -> Result<CertificateCompressionAlgorithms<'a>, TlsParseError>

Parses the offered certificate-compression algorithms.

pub fn cookie(&self) -> Result<Cookie<'a>, TlsParseError>

Parses the nonempty cookie vector.

pub fn early_data_marker(&self) -> Result<(), TlsParseError>

Validates an empty ClientHello or EncryptedExtensions early_data marker.

pub fn early_data_max_size(&self) -> Result<u32, TlsParseError>

Parses a NewSessionTicket maximum early-data size.
