Struct ProgramAccount 

pub struct ProgramAccount<'a, T: Pod + FixedLayout> { /* private fields */ }

A generic program-owned account.

Unlike HopperAccount<T> which validates against the executing program, ProgramAccount<T> validates against an arbitrary expected owner. Used for external program accounts (token accounts, mints, etc.).

Implementations

impl<'a, T: Pod + FixedLayout> ProgramAccount<'a, T>

pub fn from_account( account: &'a AccountView, expected_owner: &Address, ) -> Result<Self, ProgramError>

Construct from an AccountView, validating the owner.

pub fn from_account_unchecked(account: &'a AccountView) -> Self

Construct without owner validation (caller’s responsibility).

pub fn read(&self) -> Result<VerifiedAccount<'a, T>, ProgramError>

Read the typed overlay (immutable).

Safety

Caller must ensure no conflicting mutable borrows.

pub fn address(&self) -> &Address

The account’s address.

pub unsafe fn owner(&self) -> &Address

The account’s owner.

Safety

Caller must ensure no conflicting mutable borrows on the account.

pub fn to_account_view(&self) -> &'a AccountView

The underlying AccountView.
