Crate hopper_runtime 

Hopper Runtime – canonical semantic runtime surface.

Hopper Runtime owns the public rules, validation, typed loading, CPI semantics, and execution context that authored Hopper code targets. Hopper Native owns the raw execution boundary.

compute

Compute-budget introspection helpers.

context

Execution context for Hopper programs.

cpi

Cross-program invocation for Hopper programs.

cpi_event

Self-CPI event emission: the wire format, the verification primitives, and the runtime half of the one-line macro surface.

crank

Crank marker type emitted by the #[hopper::crank] attribute.

crypto

Runtime cryptography helpers built on Solana syscalls and precompiles.

dyn_cpi

Stack-allocated variable-length CPI builder.

Field-level layout descriptors for inspectable state contracts.

Manifest-backed foreign-account lenses.

Hopper-owned CPI instruction types.

interop

Type interop for Hopper-owned address values.

lamports

Gate-aware lamport movement.

layout

Layout contracts as runtime truth.

lazy

Runtime-typed lazy account parsing.

log

Hopper logging helpers.

memory

Hopper-owned memory helpers backed by Solana memory syscalls.

migrate

Schema-epoch in-place migration runtime.

option_byte

Zero-copy, tag-validated optional values for instruction args.

pda

Hopper-owned PDA ergonomics on top of the native runtime boundary.

pod

Pod, the canonical runtime-layer “safe to interpret from raw bytes” marker.

policy

Program-level safety policy.

proof

Proof-carrying account markers.

ref_only

Compile-proven borrow-guard constraint.

remaining

Remaining-accounts accessor with strict and passthrough modes.

rent

Rent-exemption helpers.

result

Canonical result type for Hopper programs.

return_data

CPI return-data helpers.

segment

Runtime-local segment primitive.

segment_borrow

Segment-level borrow registry for fine-grained access control.

segment_lease

RAII-leased typed segment guards.

sha256

Const SHA-256 implementation used for Hopper-owned discriminators.

syscall

Small Hopper-owned wrappers for individual runtime syscalls used directly by framework crates.

syscalls

Minimal syscall shims exposed through Hopper Runtime.

system

Hopper-native System Program CPI builders.

tail

Hybrid serialization tail for #[hopper::state(dynamic_tail = T)].

token

Hopper-native SPL Token CPI builders.

token_2022_ext

Zero-copy Token-2022 extension TLV readers.

utils

Small utilities for Hopper program authors.

write_policy

Declared write sets enforced at borrow acquisition.

zerocopy

Unified zero-copy trait family.

Macros

address

Compile-time base58 address literal.

const_pda

A program-derived address evaluated at compile time: const_pda!(PROGRAM_ID, [seed, ...], bump) is pda::const_program_address with the seed list spelled inline (each seed anything that casts to &[u8]: a byte-string literal, an Address::as_array(), a &[u8; N]). See that function for the bump contract and the soundness note.

declare_id

Declare a program’s on-chain id, mirroring the declare_id! convention every other Solana framework ships (Anchor, Pinocchio, Quasar).

default_allocator

Install the default bump allocator over the SVM heap region. Opt-in counterpart to no_allocator! for programs that need alloc on a cold path. See hopper_native::BumpAllocator.

err

Return an error immediately. Parallel to Anchor’s err!.

error

Alias for err!. Anchor-style spelling for ported code. Functionally identical.

fast_entrypoint

Backward-compatible alias for the fast Hopper entrypoint macro.

hopper_emit_cpi

Emit a Hopper event via self-CPI for reliable indexing, the manual-wiring form.

hopper_entrypoint

Declare the explicit Hopper runtime entrypoint bridge.

hopper_exact_entrypoint

Declare the count-exact program entrypoint.

hopper_fast_entrypoint

Without the simd-0321 feature the “fast” entrypoint is an alias for the standard scanning entrypoint. The SIMD-0321 gate is live on every public cluster (mainnet-beta 2026-04-01), so the two-argument form is sound to build; it stays opt-in because the r2 path measured CU-neutral against the fused scanning walk for ~368 bytes of extra .text (see the simd-0321 feature note in the workspace Cargo.toml). Build with --features simd-0321 to select the r2 entrypoint.

hopper_lazy_entrypoint

Declare the Hopper lazy entrypoint, RUNTIME-typed, matching the eager hopper_fast_entrypoint!’s layering.

hopper_log

Cheap structured logging for hot handlers.

hopper_unsafe_region

Auditable raw-pointer boundary.

layout_migrations

Compose a layout’s LayoutMigration::MIGRATIONS chain from a list of #[hopper::migrate]-emitted edge constants.

lazy_entrypoint

Backward-compatible alias for the lazy Hopper entrypoint macro.

migrate_chain

Typed multi-hop layout migration: probe-and-migrate each declared hop in declaration order, so ONE call heals an account from ANY declared starting version to the newest, the chain Quasar’s pairwise Migration<From, To> cannot express in one instruction.

msg

Backend-neutral logging macro.

no_allocator

nostd_panic_handler

program_entrypoint

Declare the canonical Hopper program entrypoint.

require

Early-return with an error if the condition is false.

require_eq

Assert two values are equal, returning an error on mismatch.

require_gt

Assert left > right strictly.

require_gte

Assert left >= right, returning the supplied error on underrun. Useful for lamport / balance checks.

require_keys_eq

Assert two public keys (or any byte slices convertible via [AsRef<[u8; 32]>]) are equal. Narrower than require_eq! but matches the ergonomic spelling ecosystem migrators coming from Anchor / Jiminy are familiar with.

require_keys_neq

Assert two public keys are not equal. Used for pinning distinct accounts (authority != user, source != destination). Same coercion and error semantics as require_keys_eq!.

require_lt

Assert left < right strictly. Anchor-parity sibling of require_gt!. Default error is ProgramError::InvalidArgument because a failed ordering check most often flags a bad user input.

require_lte

Assert left <= right. Anchor-parity sibling of require_gte!.

require_neq

Assert two values are not equal. Early-returns with the supplied error on match (or ProgramError::InvalidArgument in the short form). Symmetric with require_eq!.

seeds

Convenience macro for building an array of Seed from expressions.

Constants

MAX_TX_ACCOUNTS

SUCCESS

Traits

Pod

Marker for types that can be safely overlaid as &T / &mut T on raw account bytes at any offset.

ValuePod

Marker for Copy + Sized scalars/arrays that may be read by value from raw bytes with read_unaligned_value (alignment-independent).

Zeroable

Marker for Copy + Sized values that are valid for every bit pattern.

Functions

read_unaligned_value

Read a ValuePod scalar/array out of bytes at offset by value, tolerating any alignment (uses core::ptr::read_unaligned).
