Structs

• ApplicationMessage
  Application message received through a ProcessedMessage.
• Capabilities
  Capabilities of LeafNodes.
• ExporterSecret
• HpkeCiphertext
  7.7. Update Paths
• HpkeConfig
  Convenience tuple struct for an HPKE configuration.
• HpkeKeyPair
  Helper holding a (private, public) key pair as byte vectors.
• HpkePrivateKey
  A simple type for HPKE private keys.
• LeafNode
  This struct implements the MLS leaf node.
• LeafNodeIndex
  LeafNodeIndex references a leaf node in a tree.
• Member
  A member in the group is identified by this Member struct.
• MlsMessageIn
  Before use with the MlsGroup API, the message has to be unpacked via extract to yield its MlsMessageBodyIn.
• MlsMessageOut
  An MlsMessageOut is typically returned from an MlsGroup function and meant to be serialized and sent to the DS.
• ParentNode
  This struct implements the MLS parent node. It contains its public key, parent hash and unmerged leaves. Additionally, it may contain the private key corresponding to the public key.
• ProcessedMessage
  A message that has passed all syntax and semantics checks.
• PublicGroup
  This struct holds all public values of an MLS group.
• SecretTlsVecU8
• SecretTlsVecU16
• SecretTlsVecU24
• SecretTlsVecU32
• SecretVLBytes
  A wrapper struct around VLBytes that implements [ZeroizeOnDrop]. It behaves just like VLBytes, except that it doesn’t allow conversion into a Vec<u8>.
• SenderRatchetConfiguration
  Stores the configuration parameters for DecryptionRatchets.
• SerializedMlsGroupDeprecated
  Helper struct that contains the serializable values of an `MlsGroup.
• TlsByteSliceU8
• TlsByteSliceU16
• TlsByteSliceU24
• TlsByteSliceU32
• TlsByteVecU8
• TlsByteVecU16
• TlsByteVecU24
• TlsByteVecU32
• TlsSliceU8
• TlsSliceU16
• TlsSliceU24
• TlsSliceU32
• TlsVecU8
• TlsVecU16
• TlsVecU24
• TlsVecU32
• U24
  A 3 byte wide unsigned integer type as defined in RFC 5246.
• VLByteSlice
• VLBytes
  Variable-length encoded byte vectors. Use this struct if bytes are encoded. This is faster than the generic version.
• VerifiableCiphersuite
  A currently unknown ciphersuite.

Enums

• AeadType
  AEAD types
• Ciphersuite
  MLS ciphersuites.
• CreationFromExternalError
  Public group creation from external error.
• CryptoError
  Crypto errors.
• Error
  Errors that are thrown by this crate.
• HashType
  Hash types
• HpkeAeadType
  AEAD Types for HPKE.
• HpkeKdfType
  KDF Types for HPKE
• HpkeKemType
  KEM Types for HPKE
• MlsMessageBodyIn
  MLSMessage (Body)
• Node
  Container enum for leaf and parent nodes.
• ProcessedMessageContent
  Content of a processed message.
• ProtocolMessage
  Enum containing a message for use with process_message and an MlsGroup. Both PublicMessage and PrivateMessage implement Into<ProtocolMessage>.
• PublicGroupBuildError
  Public group builder error.
• Sender
  All possible sender types according to the MLS protocol spec.
• SignatureScheme
  SignatureScheme according to IANA TLS parameters

Traits

• DeserializeBytes
  The DeserializeBytes trait defines functions to deserialize a byte slice to a struct or enum. In contrast to [Deserialize], this trait operates directly on byte slices and can return any remaining bytes.
• OpenMlsCrypto
• OpenMlsKeyStore
  The Key Store trait
• OpenMlsProvider
  The OpenMLS Crypto Provider Trait
• OpenMlsRand
• SerializeBytes
  The SerializeBytes trait provides a function to serialize a struct or enum.
• Size
  The Size trait needs to be implemented by any struct that should be efficiently serialized. This allows to collect the length of a serialized structure before allocating memory.
