pub fn run_instructions( &mut self, instructions: &[Instruction], signers: &[&Keypair], ) -> Result<(), ClientError<<C as ClientSync>::ChannelError>>

Executes provided instructions as a transaction and returns the result.

pub fn run_instruction( &mut self, instruction: Instruction, signers: &[&Keypair], ) -> Result<(), ClientError<<C as ClientSync>::ChannelError>>

Runs a single instruction as a transaction and returns the result.

pub fn run_instructions_with_payer( &mut self, instructions: &[Instruction], payer: &Keypair, signers: &[&Keypair], ) -> Result<(), ClientError<<C as ClientSync>::ChannelError>>

Executes provided instructions as a transaction and returns the result with the provided payer keypair.

pub fn run_instruction_with_payer( &mut self, instruction: Instruction, payer: &Keypair, signers: &[&Keypair], ) -> Result<(), ClientError<<C as ClientSync>::ChannelError>>

Runs a single instruction as a transaction and returns the result with the provided payer keypair.

pub fn wait_for_tick( &mut self, ) -> Result<Hash, ClientError<<C as ClientSync>::ChannelError>>

Wait for the next tick

pub fn get_account( &mut self, address: Pubkey, ) -> Result<Account, ClientError<<C as ClientSync>::ChannelError>>

Gets account information at the given address.

pub fn token_balance( &mut self, token_account: Pubkey, ) -> Result<u64, ClientError<<C as ClientSync>::ChannelError>>

Gets how much token does this token account hold.

pub fn create_token_mint( &mut self, mint: &Keypair, authority: Pubkey, freeze_authority: Option<Pubkey>, decimals: u8, ) -> Result<(), ClientError<<C as ClientSync>::ChannelError>>

Creates a new token mint using the provided keypair.

pub fn mint_tokens( &mut self, mint: Pubkey, authority: &Keypair, recipient: Pubkey, amount: u64, ) -> Result<(), ClientError<<C as ClientSync>::ChannelError>>

Mints tokens to recipient token account with the token authority keypair.

pub fn create_associated_token_account( &mut self, owner: Pubkey, mint: Pubkey, ) -> Result<Pubkey, ClientError<<C as ClientSync>::ChannelError>>

Creates a token account using the associated token account scheme.

pub fn create_account_with_data( &mut self, account: &Keypair, data: &[u8], ) -> Result<(), ClientError<<C as ClientSync>::ChannelError>>

Creates an account with a data field. The account is required to be empty and will be owned by bpf_loader afterwards.

pub fn deploy_program( &mut self, program_account: &Keypair, data: &[u8], ) -> Result<(), ClientError<<C as ClientSync>::ChannelError>>

Create an executable account using a given keypair.

pub fn deploy_upgradeable_program( &mut self, program_account: &Keypair, buffer_account: &Keypair, authority_account: &Keypair, data: &[u8], compact: bool, ) -> Result<Pubkey, ClientError<<C as ClientSync>::ChannelError>>
