Extension

An extension is one of the Extension enum values. The enum provides a set of common functionality for all extensions.

See the individual extensions for more details on each extension.

Implementations

impl Extension

pub fn as_application_id_extension( &self, ) -> Result<&ApplicationIdExtension, ExtensionError>

Get a reference to this extension as ApplicationIdExtension. Returns an ExtensionError::InvalidExtensionType if called on an Extension that’s not an ApplicationIdExtension.

pub fn as_ratchet_tree_extension( &self, ) -> Result<&RatchetTreeExtension, ExtensionError>

Get a reference to this extension as RatchetTreeExtension. Returns an ExtensionError::InvalidExtensionType if called on an Extension that’s not a RatchetTreeExtension.

pub fn as_required_capabilities_extension( &self, ) -> Result<&RequiredCapabilitiesExtension, ExtensionError>

Get a reference to this extension as RequiredCapabilitiesExtension. Returns an ExtensionError::InvalidExtensionType error if called on an Extension that’s not a RequiredCapabilitiesExtension.

pub fn as_external_pub_extension( &self, ) -> Result<&ExternalPubExtension, ExtensionError>

Get a reference to this extension as ExternalPubExtension. Returns an ExtensionError::InvalidExtensionType error if called on an Extension that’s not a ExternalPubExtension.

pub fn as_external_senders_extension( &self, ) -> Result<&ExternalSendersExtension, ExtensionError>

Get a reference to this extension as ExternalSendersExtension. Returns an ExtensionError::InvalidExtensionType error if called on an Extension that’s not a ExternalSendersExtension.

pub const fn extension_type(&self) -> ExtensionType

Returns the ExtensionType

Trait Implementations

impl Clone for Extension

fn clone(&self) -> Extension

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Extension

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Extension

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Deserialize for Extension

fn tls_deserialize<R: Read>(bytes: &mut R) -> Result<Self, Error>

This function deserializes the bytes from the provided a std::io::Read and returns the populated struct.

fn tls_deserialize_exact(bytes: impl AsRef<[u8]>) -> Result<Self, Error>

where Self: Sized,

This function deserializes the provided bytes and returns the populated struct. All bytes must be consumed.

impl DeserializeBytes for Extension

fn tls_deserialize_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

where Self: Sized,

This function deserializes the bytes from the provided a &[u8] and returns the populated struct, as well as the remaining slice.

fn tls_deserialize_exact_bytes(bytes: &[u8]) -> Result<Self, Error>

where Self: Sized,

This function deserializes the provided bytes and returns the populated struct. All bytes must be consumed.

impl PartialEq for Extension

fn eq(&self, other: &Extension) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for &Extension

fn tls_serialize<W: Write>(&self, writer: &mut W) -> Result<usize, Error>

Serialize self and write it to the writer. The function returns the number of bytes written to writer.

fn tls_serialize_detached(&self) -> Result<Vec<u8>, Error>

Serialize self and return it as a byte vector.

impl Serialize for Extension

fn tls_serialize<W: Write>(&self, writer: &mut W) -> Result<usize, Error>

Serialize self and write it to the writer. The function returns the number of bytes written to writer.

fn tls_serialize_detached(&self) -> Result<Vec<u8>, Error>

Serialize self and return it as a byte vector.

impl Serialize for Extension

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Size for &Extension

fn tls_serialized_len(&self) -> usize

impl Size for Extension

fn tls_serialized_len(&self) -> usize

impl Eq for Extension
