[−][src]Crate cosmwasm_vm

Modules

Backend	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.
Cache
CacheOptions
Checksum	A SHA-256 checksum of a Wasm blob, used to identify a Wasm code. This must remain stable since this checksum is stored in the blockchain state.
GasInfo
GasReport
Instance
InstanceOptions
Size
Stats

BackendError
CommunicationError	An error in the communcation between contract and host. Those happen around imports and exports.
RegionValidationError	An error validating a Region
VmError

Api	Api are callbacks to system functions defined outside of the wasm modules. This is a trait to allow Mocks in the test code.
Querier
Storage	Access to the VM's backend storage, i.e. the chain

call_handle
call_handle_raw	Calls Wasm export "handle" and returns raw data from the contract. The result is length limited to prevent abuse but otherwise unchecked.
call_init
call_init_raw	Calls Wasm export "init" and returns raw data from the contract. The result is length limited to prevent abuse but otherwise unchecked.
call_migrate
call_migrate_raw	Calls Wasm export "migrate" and returns raw data from the contract. The result is length limited to prevent abuse but otherwise unchecked.
call_query
call_query_raw	Calls Wasm export "query" and returns raw data from the contract. The result is length limited to prevent abuse but otherwise unchecked.
features_from_csv	Takes a comma-separated string, splits it by commas, removes empty elements and returns a set of features. This can be used e.g. to initialize the cache.
from_slice
to_vec

BackendResult	A result type for calling into the backend. Such a call can cause non-negligible computational cost in both success and faiure case and must always have gas information attached.
CommunicationResult
RegionValidationResult
VmResult
