This DecreaseStorage context is used in the instruction which allow users to begin to unstake funds, decreasing their available storage.

Fields

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

This is the StorageConfig accounts that holds all of the admin, uploader keys.

storage_account: Account<'info, StorageAccountV2>

Parent storage account.

unstake_info: Box<Account<'info, UnstakeInfo>>

Account which stores time, epoch last unstaked

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

Account which stores SHDW when unstaking

owner: Signer<'info>

File owner, user, fee-payer Requires mutability since owner/user is fee payer.

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

User’s ATA

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

This token account serves as the account which holds user’s stake for file storage.

token_mint: Account<'info, Mint>

Token mint account

uploader: Signer<'info>

Uploader needs to sign off on decrease storage

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

Token account holding operator emission funds

system_program: Program<'info, System>

System Program

token_program: Program<'info, Token>

Token Program

rent: Sysvar<'info, Rent>

Rent Program

Trait Implementations

impl<'info> Accounts<'info> for DecreaseStorageV2<'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 DecreaseStorageV2<'info>

where 'info: 'info,

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

program_id is the currently executing program.

impl<'info> ToAccountInfos<'info> for DecreaseStorageV2<'info>

where 'info: 'info,

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

impl<'info> ToAccountMetas for DecreaseStorageV2<'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.
