Enum SystemMessage 

pub enum SystemMessage {
    Credit {
        target: AccountOwner,
        amount: Amount,
        source: AccountOwner,
    },
    Withdraw {
        owner: AccountOwner,
        amount: Amount,
        recipient: Account,
    },
    CheckpointAck {
        latest_received_cursor: Cursor,
    },
}

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: AccountOwner

amount: Amount

source: 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: Account

CheckpointAck

Sent by a chain that just executed SystemOperation::Checkpoint to each chain it has received at least one non-CheckpointAck message from since its previous checkpoint. latest_received_cursor is the position past the last bundle from the recipient that the sender has consumed. The recipient records this in finalized_sent_messages so that, when it later checkpoints its own state, it can drop already-delivered outgoing messages from its outbox dump.

Fields

latest_received_cursor: Cursor

Trait Implementations

impl Allocative for SystemMessage

fn visit<'allocative_a, 'allocative_b: 'allocative_a>( &self, visitor: &'allocative_a mut Visitor<'allocative_b>, )

impl Clone for SystemMessage

fn clone(&self) -> SystemMessage

Returns a duplicate 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

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 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
