Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Execute

Fields

contract_addr: String

msg: Binary

msg is the json-encoded ExecuteMsg struct (as raw Binary)

funds: Vec<Coin>

Dispatches a call to another contract at a known address (with known ABI).

This is translated to a MsgExecuteContract. sender is automatically filled with the current contract’s address.

Instantiate

Fields

admin: Option<String>

code_id: u64

msg: Binary

msg is the JSON-encoded InstantiateMsg struct (as raw Binary)

funds: Vec<Coin>

label: String

A human-readable label for the contract.

Valid values should:

• not be empty
• not be bigger than 128 bytes (or some chain-specific limit)
• not start / end with whitespace

Instantiates a new contracts from previously uploaded Wasm code.

The contract address is non-predictable. But it is guaranteed that when emitting the same Instantiate message multiple times, multiple instances on different addresses will be generated. See also Instantiate2.

This is translated to a MsgInstantiateContract. sender is automatically filled with the current contract’s address.

Instantiate2

Fields

admin: Option<String>

code_id: u64

label: String

A human-readable label for the contract.

Valid values should:

• not be empty
• not be bigger than 128 bytes (or some chain-specific limit)
• not start / end with whitespace

msg: Binary

msg is the JSON-encoded InstantiateMsg struct (as raw Binary)

funds: Vec<Coin>

salt: Binary

Instantiates a new contracts from previously uploaded Wasm code using a predictable address derivation algorithm implemented in [cosmwasm_std::instantiate2_address].

This is translated to a MsgInstantiateContract2. sender is automatically filled with the current contract’s address. fix_msg is automatically set to false.

Migrate

Fields

contract_addr: String

new_code_id: u64

the code_id of the new logic to place in the given contract

msg: Binary

msg is the json-encoded MigrateMsg struct that will be passed to the new code

Migrates a given contracts to use new wasm code. Passes a MigrateMsg to allow us to customize behavior.

Only the contract admin (as defined in wasmd), if any, is able to make this call.

This is translated to a MsgMigrateContract. sender is automatically filled with the current contract’s address.

UpdateAdmin

Fields

contract_addr: String

admin: String

Sets a new admin (for migrate) on the given contract. Fails if this contract is not currently admin of the target contract.

ClearAdmin

Fields

contract_addr: String

Clears the admin on the given contract, so no more migration possible. Fails if this contract is not currently admin of the target contract.

Trait Implementations

impl Clone for WasmMsg

fn clone(&self) -> WasmMsg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WasmMsg

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WasmMsg

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<WasmMsg> for CosmosMsg<T>

fn from(msg: WasmMsg) -> Self

Converts to this type from the input type.

impl JsonSchema for WasmMsg

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 WasmMsg

fn eq(&self, other: &WasmMsg) -> 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 Serialize for WasmMsg

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 WasmMsg

impl StructuralPartialEq for WasmMsg
