A system operation.

Variants

Transfer

Transfers amount units of value from the given owner’s account to the recipient. If no owner is given, try to take the units out of the unattributed account.

Fields

owner: AccountOwner

recipient: Account

amount: Amount

Claim

Claims amount units of value from the given owner’s account in the remote target chain. Depending on its configuration, the target chain may refuse to process the message.

Fields

owner: AccountOwner

target_id: ChainId

recipient: Account

amount: Amount

OpenChain(OpenChainConfig)

Creates (or activates) a new chain. This will automatically subscribe to the future committees created by admin_id.

CloseChain

Closes the chain.

ChangeOwnership

Changes the ownership of the chain.

Fields

super_owners: Vec<AccountOwner>

Super owners can propose fast blocks in the first round, and regular blocks in any round.

owners: Vec<(AccountOwner, u64)>

The regular owners, with their weights that determine how often they are round leader.

multi_leader_rounds: u32

The number of initial rounds after 0 in which all owners are allowed to propose blocks.

open_multi_leader_rounds: bool

Whether the multi-leader rounds are unrestricted, i.e. not limited to chain owners. This should only be true on chains with restrictive application permissions and an application-based mechanism to select block proposers.

timeout_config: TimeoutConfig

The timeout configuration: how long fast, multi-leader and single-leader rounds last.

ChangeApplicationPermissions(ApplicationPermissions)

Changes the application permissions configuration on this chain.

PublishModule

Publishes a new application module.

Fields

module_id: ModuleId

PublishDataBlob

Publishes a new data blob.

Fields

blob_hash: CryptoHash

VerifyBlob

Verifies that the given blob exists. Otherwise the block fails.

Fields

blob_id: BlobId

CreateApplication

Creates a new application.

Fields

module_id: ModuleId

parameters: Vec<u8>

instantiation_argument: Vec<u8>

required_application_ids: Vec<ApplicationId>

Admin(AdminOperation)

Operations that are only allowed on the admin chain.

ProcessNewEpoch(Epoch)

Processes an event about a new epoch and committee.

ProcessRemovedEpoch(Epoch)

Processes an event about a removed epoch and committee.

UpdateStreams(Vec<(ChainId, StreamId, u32)>)

Updates the event stream trackers.

Trait Implementations

impl Clone for SystemOperation

fn clone(&self) -> SystemOperation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SystemOperation

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SystemOperation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<SystemOperation> for Operation

fn from(operation: SystemOperation) -> Self

Converts to this type from the input type.

impl Hash for SystemOperation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SystemOperation

fn eq(&self, other: &SystemOperation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SystemOperation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SystemOperation

impl StructuralPartialEq for SystemOperation
