ExternalProposal

xmtp_cryptography::openmls::prelude

Struct ExternalProposal 

pub struct ExternalProposal;
Expand description

External Proposal where sender is External. A party outside the group can request to add or remove a member to the group. This proposal should then be committed by a group member. The sender must be pre configured within the group through the crate::extensions::ExternalSendersExtension

Implementations§

§

impl ExternalProposal

pub fn new_group_context_extensions<Provider>( extensions: Extensions, group_id: GroupId, epoch: GroupEpoch, signer: &impl Signer, sender_index: SenderExtensionIndex, ) -> Result<MlsMessageOut, CreateGroupContextExtProposalError<<Provider as OpenMlsProvider>::StorageError>>
where Provider: OpenMlsProvider,

Creates an external GroupContextExtensions proposal. For delivery services requesting to update the group context extensions. This proposal will have to be committed later by a group member.

§Arguments
  • extensions - a new set of extensions for the group context
  • group_id - unique group identifier of the group to join
  • epoch - group’s epoch
  • signer - of the sender to sign the message
  • sender - index of the sender of the proposal (in the crate::extensions::ExternalSendersExtension array from the Group Context)

pub fn new_remove<Provider>( removed: LeafNodeIndex, group_id: GroupId, epoch: GroupEpoch, signer: &impl Signer, sender_index: SenderExtensionIndex, ) -> Result<MlsMessageOut, ProposeRemoveMemberError<<Provider as OpenMlsProvider>::StorageError>>
where Provider: OpenMlsProvider,

Creates an external Remove proposal. For delivery services requesting to remove a client. This proposal will have to be committed later by a group member.

§Arguments
  • removed - index of the client to remove
  • group_id - unique group identifier of the group to join
  • epoch - group’s epoch
  • signer - of the sender to sign the message
  • sender - index of the sender of the proposal (in the crate::extensions::ExternalSendersExtension array from the Group Context)

pub fn new_add<Provider>( key_package: KeyPackage, group_id: GroupId, epoch: GroupEpoch, signer: &impl Signer, sender_index: SenderExtensionIndex, ) -> Result<MlsMessageOut, ProposeAddMemberError<<Provider as OpenMlsProvider>::StorageError>>
where Provider: OpenMlsProvider,

Creates an external Add proposal. For delivery services requesting to add a client. This proposal will have to be committed later by a group member.

§Arguments
  • key_package - key package of the client to add
  • group_id - unique group identifier of the group to join
  • epoch - group’s epoch
  • signer - of the sender to sign the message
  • sender - index of the sender of the proposal (in the crate::extensions::ExternalSendersExtension array from the Group Context)
