pub struct SubMsg<T = Empty> {
    pub id: u64,
    pub msg: CosmosMsg<T>,
    pub gas_limit: Option<u64>,
    pub reply_on: ReplyOn,
}
Expand description

A submessage that will guarantee a reply call on success or error, depending on the reply_on setting. If you do not need to process the result, use regular messages instead.

Note: On error the submessage execution will revert any partial state changes due to this message, but not revert any state changes in the calling contract. If this is required, it must be done manually in the reply entry point.

Fields

id: u64

An arbitrary ID chosen by the contract. This is typically used to match Replys in the reply entry point to the submessage.

msg: CosmosMsg<T>gas_limit: Option<u64>reply_on: ReplyOn

Implementations

new creates a “fire and forget” message with the pre-0.14 semantics

create a SubMsg that will provide a reply with the given id if the message returns Ok

create a SubMsg that will provide a reply with the given id if the message returns Err

create a SubMsg that will always provide a reply with the given id

Add a gas limit to the message.

Examples
let sub_msg: SubMsg = SubMsg::reply_always(msg, 1234).with_gas_limit(60_000);
assert_eq!(sub_msg.id, 1234);
assert_eq!(sub_msg.gas_limit, Some(60_000));
assert_eq!(sub_msg.reply_on, ReplyOn::Always);
