Crate cosmwasm_vm

Modules

• testing

Structs

• AnalysisReport
• 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
• DebugInfo
  Additional environmental information in a debug call.
• GasInfo
  A structure that represents gas cost to be deducted from the remaining gas. This is always needed when computations are performed outside of Wasm execution, such as calling crypto APIs or calls into the blockchain.
• GasReport
• Instance
• InstanceOptions
• Metrics
• PerModuleMetrics
• PinnedMetrics
• Size
• Stats
  Statistics about the usage of a cache instance. Those values are node specific and must not be used in a consensus critical context. When a node is hit by a client for simulations or other queries, hits and misses increase. Also a node restart will reset the values.

Enums

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

Traits

• BackendApi
  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

Functions

• call_execute
• call_execute_raw
  Calls Wasm export “execute” and returns raw data from the contract. The result is length limited to prevent abuse but otherwise unchecked.
• call_ibc_destination_callback
• call_ibc_destination_callback_raw
• call_ibc_source_callback
• call_ibc_source_callback_raw
• call_instantiate
• call_instantiate_raw
  Calls Wasm export “instantiate” 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.
• call_reply
• call_reply_raw
  Calls Wasm export “reply” and returns raw data from the contract. The result is length limited to prevent abuse but otherwise unchecked.
• call_sudo
• call_sudo_raw
  Calls Wasm export “sudo” and returns raw data from the contract. The result is length limited to prevent abuse but otherwise unchecked.
• capabilities_from_csv
  Takes a comma-separated string, splits it by commas, removes empty elements and returns a set of capabilities. This can be used e.g. to initialize the cache.
• from_slice
  Deserializes JSON data into a document of type T.
• to_vec

Type Aliases

• 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
