Struct core_crypto::prelude::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 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 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 async fn take_ratchet_tree( self, backend: &impl OpenMlsCryptoProvider, sender: bool, ) -> Result<RatchetTree, GroupInfoError>

Do whatever it takes not to clone the RatchetTree

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<(), Error>

Formats the value using the given formatter.

impl Deserialize for VerifiableGroupInfo

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

where R: Read,

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 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

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

where T: VerifiedStruct<Self>,

Verifies the payload against the given credential. The signature is fetched via the [Verifiable::signature()] function and the payload via [Verifiable::unsigned_payload()].

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

Verifies the payload against the given credential. The signature is fetched via the [Verifiable::signature()] function and the payload via [Verifiable::unsigned_payload()].
