Expand description
Accounts struct for cancelling a stream.
Fields§
§stream: Account<'info, Stream>
Stream PDA account.
signer: Signer<'info>
Signer wallet. Either the sender or the receiver can cancel the stream till it’s solvent. After insolvency, anyone can cancel.
sender: UncheckedAccount<'info>
Stream sender account.
CHECK: Only 1 check is needed which is in the constraint. That is enough to verify that we are sending the funds to the stream sender.
mint: Box<Account<'info, Mint>>
SPL token mint account.
signer_token: Box<Account<'info, TokenAccount>>
Associated token account of the signer.
sender_token: Box<Account<'info, TokenAccount>>
Associated token account of the sender.
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.

pub fn transfer_from_escrow_to_sender( &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 sender.

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. Read moresource§impl<'info> AccountsExit<'info> for Cancel<'info>where

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.Auto Trait Implementations§
