Struct MlsService 

pub struct MlsService<S: DeMlsStorage> { /* private fields */ }

Main MLS service - unified API for all MLS operations.

Groups are managed internally by group ID string. The service handles:

• Identity initialization and management
• Key package generation
• Group creation and joining
• Message encryption and decryption
• Steward commit operations

Implementations

impl<S> MlsService<S>

where S: DeMlsStorage<MlsStorage = MemoryStorage>,

pub fn new(storage: S) -> Self

Create a new MLS service with the given storage backend.

pub fn init(&self, wallet: Address) -> Result<()>

Initialize identity from wallet address.

Creates MLS credentials and signing keys from the wallet address. Call this once before using any other methods.

pub fn wallet_hex(&self) -> String

Get the wallet address as a checksummed hex string (“0x…”).

pub fn generate_key_package(&self) -> Result<KeyPackageBytes>

Generate a key package for joining a group.

Key packages are single-use and should be regenerated after each join.

pub fn create_group(&self, group_id: &str) -> Result<()>

Create a new MLS group.

The group name becomes the MLS group ID. The creator becomes the only member and is typically the steward.

pub fn join_group(&self, welcome_bytes: &[u8]) -> Result<String>

Join a group from a welcome message.

Returns the group ID on success. The welcome must be for us (contain one of our key package references).

pub fn is_welcome_for_us(&self, welcome_bytes: &[u8]) -> Result<bool>

Check if a welcome message is for us (without joining).

Returns true if the welcome contains one of our key package references.

pub fn members(&self, group_id: &str) -> Result<Vec<Vec<u8>>>

Get all current group members as wallet addresses.

pub fn encrypt(&self, group_id: &str, plaintext: &[u8]) -> Result<Vec<u8>>

Encrypt an application message for the group.

Returns MLS ciphertext that only group members can decrypt.

pub fn decrypt( &self, group_id: &str, ciphertext: &[u8], ) -> Result<DecryptResult>

Decrypt/process an inbound MLS message.

Handles application messages, proposals, and commits.

pub fn commit( &self, group_id: &str, updates: &[GroupUpdate], ) -> Result<CommitResult>

Create proposals for membership changes and commit them.

This is the core steward operation: takes a list of add/remove operations, creates MLS proposals, and commits them in a batch.
