Struct RemainingAccounts 

pub struct RemainingAccounts<'a> { /* private fields */ }

Zero-allocation remaining-accounts view.

Construct via RemainingAccounts::strict or RemainingAccounts::passthrough from the declared slice and the full accounts slice. #[hopper::context] emits ctx.remaining_accounts() and ctx.remaining_accounts_passthrough() accessors that wire these up for you.

Implementations

impl<'a> RemainingAccounts<'a>

pub fn strict( declared: &'a [&'a AccountView], remaining: &'a [&'a AccountView], ) -> Self

Build a strict accessor. Iteration rejects duplicates.

pub fn passthrough( declared: &'a [&'a AccountView], remaining: &'a [&'a AccountView], ) -> Self

Build a passthrough accessor. Iteration preserves duplicates.

pub fn len(&self) -> usize

Length of the remaining slice, irrespective of mode.

pub fn is_empty(&self) -> bool

True when there are no remaining accounts.

pub fn mode(&self) -> RemainingMode

The active duplicate-handling policy for this view.

pub fn get(&self, index: usize) -> Result<Option<&'a AccountView>, ProgramError>

Random access by index. Passthrough returns the slot as is; strict returns an error when the resolved slot aliases a previously-seen account (declared or yielded before index).

pub fn iter(&self) -> RemainingIter<'a>

Sequential iterator. Yields each account in declaration order, errors on duplicates in strict mode, preserves them in passthrough mode.
