impl<'info> Accounts<'info> for UncheckedAccount<'info>
sourcefn try_accounts(
_program_id: &Pubkey,
accounts: &mut &[AccountInfo<'info>],
_ix_data: &[u8]
) -> Result<Self, ProgramError>
fn try_accounts(
_program_id: &Pubkey,
accounts: &mut &[AccountInfo<'info>],
_ix_data: &[u8]
) -> Result<Self, ProgramError>
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 more

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. Read more
