A system message meant to be executed on a remote chain.

Variants

Credit

Credits amount units of value to the account target – unless the message is bouncing, in which case source is credited instead.

Fields

target: Option<AccountOwner>

amount: Amount

source: Option<AccountOwner>

Withdraw

Withdraws amount units of value from the account and starts a transfer to credit the recipient. The message must be properly authenticated. Receiver chains may refuse it depending on their configuration.

Fields

owner: AccountOwner

amount: Amount

recipient: Recipient

OpenChain(OpenChainConfig)

Creates (or activates) a new chain.

CreateCommittee

Adds a new epoch and committee.

Fields

epoch: Epoch

committee: Committee

RemoveCommittee

Removes an old committee.

Fields

epoch: Epoch

Subscribe

Subscribes to a channel.

Fields

id: ChainId

subscription: ChannelSubscription

Unsubscribe

Unsubscribes from a channel.

Fields

id: ChainId

subscription: ChannelSubscription

ApplicationCreated

Notifies that a new application was created.

RegisterApplications

Shares information about some applications to help the recipient use them. Applications must be registered after their dependencies.

Fields

applications: Vec<UserApplicationDescription>

RequestApplication(UserApplicationId)

Requests a RegisterApplication message from the target chain to register the specified application on the sender chain.

Trait Implementations

impl Clone for SystemMessage

fn clone(&self) -> SystemMessage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SystemMessage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SystemMessage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<SystemMessage> for Message

fn from(message: SystemMessage) -> Self

Converts to this type from the input type.

impl Hash for SystemMessage

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 SystemMessage

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for SystemMessage

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 SystemMessage

impl StructuralPartialEq for SystemMessage
