Struct superstream::WithdrawAndChangeRecipient

pub struct WithdrawAndChangeRecipient<'info> {
    pub stream: Account<'info, Stream>,
    pub signer: Signer<'info>,
    pub mint: Box<Account<'info, Mint>>,
    pub recipient_token: Box<Account<'info, TokenAccount>>,
    pub escrow_token: Box<Account<'info, TokenAccount>>,
    pub token_program: Program<'info, Token>,
}

Accounts struct for withdrawing recipient funds from a stream and changing recipient of a stream.

Fields

stream: Account<'info, Stream>

Stream PDA account.

signer: Signer<'info>

Signer wallet. Anybody can call the withdraw method. The recipient of the withdrawn amount is not related to the signer. Recipient is passed as an argument, based on which the stream PDA is accessed, so if a malicious user tries to send themselves as a recipient, but a different stream account, the constraint for the stream account will fail.

mint: Box<Account<'info, Mint>>

SPL token mint account.

recipient_token: Box<Account<'info, TokenAccount>>

Associated token account of the recipient.

escrow_token: Box<Account<'info, TokenAccount>>

Associated token escrow account holding the funds for this stream.

token_program: Program<'info, Token>

SPL token program.

Implementations

impl<'info> WithdrawAndChangeRecipient<'info>

pub fn transfer_from_escrow( &self, seed: u64, name: &str, bump: u8, amount: u64 ) -> Result<()>

Transfer funds from the associated token escrow account holding the funds for this stream to the associated token account of the recipient.

Trait Implementations

impl<'info> Accounts<'info> for WithdrawAndChangeRecipient<'info>where 'info: 'info,

fn try_accounts( __program_id: &Pubkey, __accounts: &mut &[AccountInfo<'info>], __ix_data: &[u8], __bumps: &mut BTreeMap<String, u8>, __reallocs: &mut BTreeSet<Pubkey> ) -> Result<Self>

Returns the validated accounts struct. What constitutes “valid” is program dependent. However, users of these types should never have to worry about account substitution attacks. For example, if a program expects a Mint account from the SPL token program in a particular field, then it should be impossible for this method to return Ok if any other account type is given–from the SPL token program or elsewhere.

impl<'info> AccountsExit<'info> for WithdrawAndChangeRecipient<'info>where 'info: 'info,

fn exit(&self, program_id: &Pubkey) -> Result<()>

program_id is the currently executing program.

impl<'info> ToAccountInfos<'info> for WithdrawAndChangeRecipient<'info>where 'info: 'info,

fn to_account_infos(&self) -> Vec<AccountInfo<'info>>

impl<'info> ToAccountMetas for WithdrawAndChangeRecipient<'info>

fn to_account_metas(&self, is_signer: Option<bool>) -> Vec<AccountMeta>

is_signer is given as an optional override for the signer meta field. This covers the edge case when a program-derived-address needs to relay a transaction from a client to another program but sign the transaction before the relay. The client cannot mark the field as a signer, and so we have to override the is_signer meta field given by the client.
