Struct BranchInfo 

pub struct BranchInfo { /* private fields */ }

Available on 32-bit or 64-bit only.

The information a sub-group branch needs from its parent group.

Export this from the parent group with MlsGroup::branch_info and pass it to the subgroup branch APIs: the sender uses MlsGroupBuilder::branch and the receiver uses StagedWelcome::build_from_branch.

This is an owned snapshot, so it does not borrow the parent group and can outlive it.

This carries the parent’s resumption PSK secret, which is sensitive key material and must be handled accordingly.

Implementations

impl BranchInfo

pub fn version(&self) -> ProtocolVersion

The protocol version of the parent group.

pub fn ciphersuite(&self) -> Ciphersuite

The ciphersuite of the parent group.

pub fn group_id(&self) -> &GroupId

The group ID of the parent group.

pub fn epoch(&self) -> GroupEpoch

The epoch of the parent group from which this branch is taken.

pub fn member_credentials(&self) -> &[Credential]

The credentials of the parent group’s members, used by the receiver to check that every sub-group member is also a parent-group member.
