Implementations

impl VariableRepositoryContract

pub fn init( &mut self, fiat_conversion: Address, bid_escrow_wallet: Address, voting_ids: Address )

Constructor function.

Note

Initializes contract elements:

• Sets the default configuration of the Repository
• Sets [caller] as the owner of the contract.
• Adds [caller] to the whitelist.

Events

• OwnerChanged,
• AddedToWhitelist,
• multiple ValueUpdated events, one per value of the default repository configuration.

pub fn update_at( &mut self, key: String, value: Bytes, activation_time: Option<u64> )

Inserts or updates the value under the given key.

Note

• The activation time is represented as a unix timestamp.
• If the activation time is None the value is updated immediately.
• If some future time in the future is passed as an argument, the Self::get function returns the previously set value.

Events

• ValueUpdated.

Errors

• NotWhitelisted if the caller is not a whitelisted user.
• ActivationTimeInPast if the activation time has passed already.

pub fn get(&self, key: String) -> Option<Bytes>

Returns the value stored under the given key.

If the key does not exist, the None value is returned.

pub fn get_full_value(&self, key: String) -> Option<Record>

Returns the full (current and future) value stored under the given key. See Record.

If the key does not exist, the None value is returned.

pub fn get_key_at(&self, index: u32) -> Option<String>

Returns the value stored under the given index.

Every freshly added key has the previous key index increased by 1. The index range is 0 to #keys-1.

If the given index exceeds #keys-1 the None value is returned.

pub fn keys_count(&self) -> u32

Returns the number of existing keys in the Repository.

pub fn all_variables(&self) -> BTreeMap<String, Bytes>

Reads all the stored variables and returns a map key to value.

pub fn is_whitelisted(&self, address: Address) -> bool

Checks whether the given address is added to the whitelist. .

pub fn get_owner(&self) -> Option<Address>

Returns the address of the current owner. .

pub fn propose_new_owner(&mut self, owner: Address)

Changes the ownership of the contract. Transfers ownership to the owner. Only the current owner is permitted to call this method.

pub fn accept_new_owner(&mut self)

Accepts the new owner proposition. This can be called only by the proposed owner.

pub fn add_to_whitelist(&mut self, address: Address)

Adds a new address to the whitelist.

pub fn remove_from_whitelist(&mut self, address: Address)

Remove address from the whitelist.
