Struct VerifiableGroupInfo

pub struct VerifiableGroupInfo { /* private fields */ }

A type that represents a group info of which the signature has not been verified. It implements the Verifiable trait and can be turned into a group info by calling verify(...) with the signature key of the Credential. When receiving a serialized group info, it can only be deserialized into a VerifiableGroupInfo, which can then be turned into a group info as described above.

Implementations

impl VerifiableGroupInfo

pub fn new( group_context: GroupContext, extensions: Extensions, confirmation_tag: ConfirmationTag, signer: LeafNodeIndex, signature: Signature, ) -> Self

Create a new VerifiableGroupInfo from its contents.

pub fn ciphersuite(&self) -> Ciphersuite

Get (unverified) ciphersuite of the verifiable group info.

Note: This method should only be used when necessary to verify the group info signature.

pub fn extensions(&self) -> &Extensions

Get (unverified) extensions of the verifiable group info.

Note: This method should only be used when necessary to verify the group info signature.

pub fn group_id(&self) -> &GroupId

Get (unverified) group ID of the verifiable group info.

Note: This method should only be used when necessary to verify the group info signature.

pub fn epoch(&self) -> GroupEpoch

Get (unverified) epoch of the verifiable group info.

Note: This method should only be used when necessary to verify the group info signature.

Trait Implementations

impl Clone for VerifiableGroupInfo

fn clone(&self) -> VerifiableGroupInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VerifiableGroupInfo

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

Formats the value using the given formatter.

impl Deserialize for VerifiableGroupInfo

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 VerifiableGroupInfo

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

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 VerifiableGroupInfo

fn eq(&self, other: &VerifiableGroupInfo) -> 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 Size for &VerifiableGroupInfo

fn tls_serialized_len(&self) -> usize

impl Size for VerifiableGroupInfo

fn tls_serialized_len(&self) -> usize

impl Verifiable for VerifiableGroupInfo

type VerifiedStruct = GroupInfo

The type used for representing the verified data. Must implement the marker trait VerifiedStruct.

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

Return the unsigned, serialized payload that should be verified.

fn signature(&self) -> &Signature

A reference to the signature to be verified.

fn label(&self) -> &str

Return the string label used for labeled verification.

fn verify( self, crypto: &impl OpenMlsCrypto, pk: &OpenMlsSignaturePublicKey, ) -> Result<Self::VerifiedStruct, SignatureError>

Verifies the payload against the given credential. Usually this is implemented by first checking that self.verify_no_out() does not return an error, and then converting the value into Self::VerifiedStruct.

fn verify_no_out( &self, crypto: &impl OpenMlsCrypto, pk: &OpenMlsSignaturePublicKey, ) -> Result<(), SignatureError>

Verifies the payload against the given public key. The signature is fetched via the Verifiable::signature() function and the payload via Verifiable::unsigned_payload().
