Identity

Enum Identity 

Source 
pub enum Identity {
    V0(IdentityV0),
}
Expand description

The identity is not stored inside of drive, because of this, the serialization is mainly for transport, the serialization of the identity will include the version, so no passthrough or untagged is needed here

Implementations§

Source§

impl Identity

Source

pub fn hash(&self) -> Result<Vec<u8>, ProtocolError>

Computes the hash of an identity

Source

pub fn default_versioned( platform_version: &PlatformVersion, ) -> Result<Identity, ProtocolError>

Source

pub fn new_with_id_and_keys( id: Identifier, public_keys: BTreeMap<KeyID, IdentityPublicKey>, platform_version: &PlatformVersion, ) -> Result<Identity, ProtocolError>

Created a new identity based on asset locks and keys

Source

pub fn new_with_input_addresses_and_keys( inputs: &BTreeMap<PlatformAddress, (AddressNonce, Credits)>, public_keys: BTreeMap<KeyID, IdentityPublicKey>, platform_version: &PlatformVersion, ) -> Result<Identity, ProtocolError>

Create a new identity using input PlatformAddresses.

This function derives the identity ID from the provided input addresses.

§Arguments
  • inputs - A map of PlatformAddress to (AddressNonce, Credits). The identity id is derived from the addresses and nonces (credits are ignored for the id derivation). The nonces should represent state after creation of the identity (e.g. be incremented by 1).
  • public_keys - A map of KeyID to IdentityPublicKey tuples representing the public keys for the identity.
  • platform_version - The platform version to use for identity creation.
§Returns
  • Result<Identity, ProtocolError> - Returns the newly created Identity or a ProtocolError if the operation fails.
