pub struct Extern<S: Storage, A: Api, Q: Querier> {
    pub storage: S,
    pub api: A,
    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

storage: Sapi: Aquerier: Q

Implementations

source

impl<S: Storage, A: Api, Q: Querier> Extern<S, A, Q>

source

pub fn change_querier<T: Querier, F: Fn(Q) -> T>(
self,
transform: F
) -> Extern<S, A, T>

change_querier is a helper mainly for test code when swapping out the Querier from the auto-generated one from mock_dependencies. This changes the type of Extern so replaces requires some boilerplate.
