Struct cosmwasm_std::SubMsg

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

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>

Gas limit measured in Cosmos SDK gas.

reply_on: ReplyOn

Implementations

impl<T> SubMsg<T>

pub fn new(msg: impl Into<CosmosMsg<T>>) -> Self

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

pub fn reply_on_success(msg: impl Into<CosmosMsg<T>>, id: u64) -> Self

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

pub fn reply_on_error(msg: impl Into<CosmosMsg<T>>, id: u64) -> Self

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

pub fn reply_always(msg: impl Into<CosmosMsg<T>>, id: u64) -> Self

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

pub fn with_gas_limit(self, limit: u64) -> Self

Add a gas limit to the message. This gas limit measured in Cosmos SDK gas.

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);

Trait Implementations

impl<T: Clone> Clone for SubMsg<T>

fn clone(&self) -> SubMsg<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for SubMsg<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for SubMsg<T>

where T: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: JsonSchema> JsonSchema for SubMsg<T>

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<T: PartialEq> PartialEq for SubMsg<T>

fn eq(&self, other: &SubMsg<T>) -> 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<T> Serialize for SubMsg<T>

where T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
