Struct Wallet

pub struct Wallet { /* private fields */ }

A FuelVM-compatible wallet that can be used to list assets, balances and more.

Note that instances of the Wallet type only know their public address, and as a result can only perform read-only operations.

In order to sign messages or send transactions, a Wallet must first call Wallet::unlock with a valid private key to produce a WalletUnlocked.

Implementations

impl Wallet

pub fn from_address(address: Bech32Address, provider: Option<Provider>) -> Self

Construct a Wallet from its given public address.

pub fn get_provider(&self) -> Result<&Provider, WalletError>

pub fn set_provider(&mut self, provider: Provider)

pub fn address(&self) -> &Bech32Address

pub async fn get_transactions( &self, request: PaginationRequest<String>, ) -> Result<PaginatedResult<TransactionResponse, String>>

pub async fn get_asset_inputs_for_amount( &self, asset_id: AssetId, amount: u64, witness_index: u8, ) -> Result<Vec<Input>>

Returns a vector consisting of Input::Coins and Input::Messages for the given asset ID and amount. The witness_index is the position of the witness (signature) in the transaction’s list of witnesses. In the validation process, the node will use the witness at this index to validate the coins returned by this method.

pub fn get_asset_outputs_for_amount( &self, to: &Bech32Address, asset_id: AssetId, amount: u64, ) -> Vec<Output>

Returns a vector containing the output coin and change output given an asset and amount

pub async fn get_coins(&self, asset_id: AssetId) -> Result<Vec<Coin>>

Gets all unspent coins of asset asset_id owned by the wallet.

pub async fn get_spendable_resources( &self, asset_id: AssetId, amount: u64, ) -> Result<Vec<Resource>>

Get some spendable resources (coins and messages) of asset asset_id owned by the wallet that add up at least to amount amount. The returned coins (UTXOs) are actual coins that can be spent. The number of UXTOs is optimized to prevent dust accumulation.

pub async fn get_asset_balance(&self, asset_id: &AssetId) -> Result<u64>

Get the balance of all spendable coins asset_id for address address. This is different from getting coins because we are just returning a number (the sum of UTXOs amount) instead of the UTXOs.

pub async fn get_balances(&self) -> Result<HashMap<String, u64>>

Get all the spendable balances of all assets for the wallet. This is different from getting the coins because we are only returning the sum of UTXOs coins amount and not the UTXOs coins themselves.

pub async fn get_messages(&self) -> Result<Vec<InputMessage>>

pub fn unlock(self, private_key: SecretKey) -> WalletUnlocked

Unlock the wallet with the given private_key.

The private key will be stored in memory until wallet.lock() is called or until the wallet is dropped.

Trait Implementations

impl Clone for Wallet

fn clone(&self) -> Wallet

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Wallet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
