Module cpi 

Cross-program invocation for Hopper programs.

Provides both checked (borrow-validating) and unchecked invoke paths. Hopper uses direct runtime syscalls after Hopper-level validation.

Re-exports

pub use crate::instruction::Seed;

pub use crate::instruction::Signer;

Constants

MAX_CPI_ACCOUNTS

Hard ceiling on the number of account-infos in any single CPI.

MAX_RETURN_DATA

Maximum return data size (1 KiB).

MAX_STATIC_CPI_ACCOUNTS

Default stack-sized ceiling for a static CPI call.

Functions

invoke

Invoke a CPI with full validation.

invoke_borrow_checked

Invoke a CPI with borrow-state validation only, the Pinocchio-equivalent mid tier.

invoke_checked

Explicit alias for Hopper’s validated CPI path.

invoke_signed

Invoke a signed CPI with full validation.

invoke_signed_borrow_checked

Invoke a signed CPI with borrow-state validation only, the Pinocchio-equivalent mid tier.

invoke_signed_checked

Explicit alias for Hopper’s validated signed CPI path.

invoke_signed_deduped

Invoke a CPI whose account-info list has been deduplicated by pubkey, the SIMD-0339 fewest-infos-per-CPI optimization.

invoke_signed_unchecked^⚠

Invoke a signed CPI without borrow validation.

invoke_signed_with_bounds

Signed invoke with a dynamic number of accounts (bounded by const generic).

invoke_unchecked^⚠

Invoke a CPI without borrow validation (lowest CU cost).

invoke_with_bounds

Invoke with a dynamic number of accounts (bounded by const generic).

set_return_data

Set return data for the current instruction.
