Struct add_decimals::InitializeWrapper

pub struct InitializeWrapper<'info> {
    pub wrapper: Account<'info, WrappedToken>,
    pub wrapper_underlying_tokens: Account<'info, TokenAccount>,
    pub underlying_mint: Account<'info, Mint>,
    pub wrapper_mint: Account<'info, Mint>,
    pub payer: Signer<'info>,
    pub rent: Sysvar<'info, Rent>,
    pub system_program: Program<'info, System>,
}

Accounts for initializing a new wrapper.

Fields

wrapper: Account<'info, WrappedToken>

The WrappedToken account.

wrapper_underlying_tokens: Account<'info, TokenAccount>

Token account containing the underlying tokens.

underlying_mint: Account<'info, Mint>

Mint of the underlying token.

wrapper_mint: Account<'info, Mint>

Mint of the wrapper.

payer: Signer<'info>

Payer of the newly created decimal wrapper.

rent: Sysvar<'info, Rent>

Rent sysvar. Required for initialization.

system_program: Program<'info, System>

System program. Required for initialization.

Implementations

impl<'info> InitializeWrapper<'info>

pub fn validate(&self) -> ProgramResult

Validates ownership of the accounts of the wrapper.

Trait Implementations

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

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.

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

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

program_id is the currently executing program.

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

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

impl<'info> ToAccountMetas for InitializeWrapper<'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.
