Struct cosmwasm_std::IbcCallbackRequest

pub struct IbcCallbackRequest { /* private fields */ }

This is just a type representing the data that has to be sent with the IBC message to receive callbacks. It should be serialized and sent with the IBC message. The specific field and format to send it in can vary depending on the IBC message, but is usually the memo field by convention.

See IbcSourceCallbackMsg and IbcDestinationCallbackMsg for more details.

Example

Using TransferMsgBuilder:

use cosmwasm_std::{
    to_json_string, Coin, IbcCallbackRequest, TransferMsgBuilder, IbcSrcCallback, IbcTimeout, Response,
    Timestamp,
};

let _msg = TransferMsgBuilder::new(
    "channel-0".to_string(),
    "cosmos1example".to_string(),
    Coin::new(10u32, "ucoin"),
    Timestamp::from_seconds(12345),
)
.with_src_callback(IbcSrcCallback {
    address: env.contract.address,
    gas_limit: None,
})
.build();

Manual serialization:

use cosmwasm_std::{
    to_json_string, Coin, IbcCallbackRequest, IbcMsg, IbcSrcCallback, IbcTimeout, Response,
    Timestamp,
};

let _transfer = IbcMsg::Transfer {
    to_address: "cosmos1example".to_string(),
    channel_id: "channel-0".to_string(),
    amount: Coin::new(10u32, "ucoin"),
    timeout: Timestamp::from_seconds(12345).into(),
    memo: Some(to_json_string(&IbcCallbackRequest::source(IbcSrcCallback {
        address: env.contract.address,
        gas_limit: None,
    })).unwrap()),
};

Implementations

impl IbcCallbackRequest

pub fn both(src_callback: IbcSrcCallback, dest_callback: IbcDstCallback) -> Self

Use this if you want to execute callbacks on both the source and destination chain.

pub fn source(src_callback: IbcSrcCallback) -> Self

Use this if you want to execute callbacks on the source chain, but not the destination chain.

pub fn destination(dest_callback: IbcDstCallback) -> Self

Use this if you want to execute callbacks on the destination chain, but not the source chain.

Trait Implementations

impl Clone for IbcCallbackRequest

fn clone(&self) -> IbcCallbackRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IbcCallbackRequest

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IbcCallbackRequest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for IbcCallbackRequest

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(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for IbcCallbackRequest

fn eq(&self, other: &IbcCallbackRequest) -> 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 IbcCallbackRequest

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 IbcCallbackRequest
