Macros

create_entry_points	This macro generates the boilerplate required to call into the contract-specific logic from the entry-points to the Wasm module.
create_entry_points_with_migration	This macro is very similar to the create_entry_points macro, except it also requires the migrate method:

Structs

AllBalanceResponse
AllDelegationsResponse	DelegationsResponse is data format returned from StakingRequest::AllDelegations query
Attribute	An key value pair that is used in the context of event attributes in logs
BalanceResponse
Binary	Binary is a wrapper around Vec to add base64 de/serialization with serde. It also adds some helper methods to help encode inline.
BlockInfo
BondedDenomResponse	BondedDenomResponse is data format returned from StakingRequest::BondedDenom query
CanonicalAddr
Coin
Context
ContractInfo
Decimal	A fixed-point decimal value with 18 fractional digits, i.e. Decimal(1_000_000_000_000_000_000) == 1.0
Delegation	Delegation is basic (cheap to query) data about a delegation
Deps
DepsMut
Empty	An empty struct that serves as a placeholder in different places, such as contracts that don't set a custom message.
Env
FullDelegation	FullDelegation is all the info on the delegation, some (like accumulated_reward and can_redelegate) is expensive to query
HandleResponse
HumanAddr
InitResponse
MemoryStorage
MessageInfo	MessageInfo is sent with init, handle, and migrate calls, but not with queries. It contains the essential info for authorization - identity of the call, and payment
MigrateResponse
OwnedDeps	Holds all external dependencies of the contract. Designed to allow easy dependency injection at runtime. This cannot be copied or cloned since it would behave differently for mock storages and a bridge storage in the VM.
QuerierWrapper
Uint128
Validator
ValidatorsResponse	ValidatorsResponse is data format returned from StakingRequest::Validators query

Enums

BankMsg
BankQuery
ContractResult	This is the final result type that is created and serialized in a contract for every init/handle/migrate call. The VM then deserializes this type to distinguish between successful and failed executions.
CosmosMsg
QueryRequest
StakingMsg
StakingQuery
StdError	Structured error type for init, handle and query.
SystemError	SystemError is used for errors inside the VM and is API friendly (i.e. serializable).
SystemResult	This is the outer result type returned by a querier to the contract.
WasmMsg
WasmQuery

Traits

Api	Api are callbacks to system functions implemented outside of the wasm modules. Currently it just supports address conversion but we could add eg. crypto functions here.
ByteArray	A marker trait for [u8; $N], which is needed as long as https://rust-lang.github.io/rfcs/2000-const-generics.html is not stable.
CustomQuery	A trait that is required to avoid conflicts with other query types like BankQuery and WasmQuery in generic implementations. You need to implement it in your custom query type.
Querier
Storage	Storage provides read and write access to a persistent storage. If you only want to provide read access, provide &Storage

Functions

attr	Creates a new Attribute.
coin	A shorthand constructor for Coin
coins	A shortcut constructor for a set of one denomination of coins
from_binary
from_slice
has_coins	has_coins returns true if the list of coins has at least the required amount
to_binary
to_vec

Type Definitions

HandleResult
InitResult
MigrateResult
QuerierResult	A short-hand alias for the two-level query result (1. accessing the contract, 2. executing query in the contract)
QueryResponse
QueryResult
StdResult	The return type for init, handle and query. Since the error type cannot be serialized to JSON, this is only available within the contract and its unit tests.
