Enum IbcSourceCallbackMsg

pub enum IbcSourceCallbackMsg {
    Acknowledgement(IbcAckCallbackMsg),
    Timeout(IbcTimeoutCallbackMsg),
}

The type of IBC source callback that is being called.

IBC source callbacks are needed for cases where your contract triggers the sending of an IBC packet through some other message (i.e. not through crate::IbcMsg::SendPacket) and needs to know whether or not the packet was successfully received on the other chain. A prominent example is the crate::IbcMsg::Transfer message. Without callbacks, you cannot know whether the transfer was successful or not.

Note that there are some prerequisites that need to be fulfilled to receive source callbacks:

• The contract must implement the ibc_source_callback entrypoint.
• The IBC application in the source chain must have support for the callbacks middleware.
• You have to add serialized IbcCallbackRequest to a specific field of the message. For IbcMsg::Transfer, this is the memo field and it needs to be json-encoded.
• The receiver of the callback must also be the sender of the message.

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IbcSourceCallbackMsg

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for IbcSourceCallbackMsg

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

impl PartialEq for IbcSourceCallbackMsg

fn eq(&self, other: &IbcSourceCallbackMsg) -> 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.
