A trait providing methods to read and write (manipulate) accounts

Required Methods

fn set_account(&mut self, lamports: u64) -> Keypair

Create an empty account and add lamports to it

fn set_account_custom(&mut self, address: &Pubkey, account: &AccountSharedData)

Create or overwrite a custom account, subverting normal runtime checks.

fn set_token_account( &mut self, mint: Pubkey, owner: Pubkey, amount: u64, delegate: Option<Pubkey>, is_native: Option<u64>, delegated_amount: u64, close_authority: Option<Pubkey>, ) -> Pubkey

Create an SPL token account

fn set_mint_account( &mut self, decimals: u8, owner: &Pubkey, freeze_authority: Option<Pubkey>, ) -> Pubkey

Create an SPL mint account

fn payer(&self) -> Keypair

Get the Keypair of the client’s payer account

fn get_account( &mut self, key: &Pubkey, ) -> Result<Option<Account>, FuzzClientError>

Get the account at the given address

fn get_accounts( &mut self, metas: &[AccountMeta], ) -> Result<Vec<Option<Account>>, FuzzClientErrorWithOrigin>

Get accounts based on the supplied meta information

fn get_last_blockhash(&self) -> Hash

Get last blockhash

fn get_rent(&mut self) -> Result<Rent, FuzzClientError>

Get the cluster rent

fn process_transaction( &mut self, transaction: impl Into<VersionedTransaction>, ) -> Result<(), FuzzClientError>

Send a transaction and return until the transaction has been finalized or rejected.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
