Struct MutableFees 

pub struct MutableFees<'info> {
    pub storage_config: Box<Account<'info, StorageConfig>>,
    pub admin: Signer<'info>,
}

This MutableFees context is used to initialize the account which stores Shadow Drive configuration data including storage costs, admin pubkeys.

Fields

storage_config: Box<Account<'info, StorageConfig>>

This account is a PDA that holds the SPL’s staking and slashing policy. This is the account that signs transactions on behalf of the program to distribute staking rewards.

admin: Signer<'info>

This account is the SPL’s staking policy admin. Must be either freeze or mint authority

Trait Implementations

impl<'info> Accounts<'info> for MutableFees<'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 MutableFees<'info>

where 'info: 'info,

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

program_id is the currently executing program.

impl<'info> ToAccountInfos<'info> for MutableFees<'info>

where 'info: 'info,

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

impl<'info> ToAccountMetas for MutableFees<'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.
