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

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.

Fields

contract_addr: String

msg: Binary

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

funds: Vec<Coin>

Instantiate

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.

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

Instantiate2

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.

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

Migrate

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.

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

UpdateAdmin

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

Fields

contract_addr: String

admin: String

ClearAdmin

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

Fields

contract_addr: String

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, __derive_more_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(generator: &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

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 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
