Struct cosmwasm_vm::Backend[−][src]

pub struct Backend<A: BackendApi, S: Storage, Q: Querier> {
    pub api: A,
    pub storage: S,
    pub querier: Q,
}

Expand description

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.

Fields

api: Astorage: Squerier: Q
