Trait cosmwasm_std::Storage

pub trait Storage: ReadonlyStorage {
    fn set(&mut self, key: &[u8], value: &[u8]) -> StdResult<()>;
    fn remove(&mut self, key: &[u8]) -> StdResult<()>;
}

Required methods

fn set(&mut self, key: &[u8], value: &[u8]) -> StdResult<()>

fn remove(&mut self, key: &[u8]) -> StdResult<()>

Removes a database entry at key.

The current interface does not allow to differentiate between a key that existed before and one that didn't exist. See https://github.com/CosmWasm/cosmwasm/issues/290
