Module raw_input 

Raw loader input parsing for Hopper Native.

This is the single source of truth for Solana loader input decoding. It owns duplicate-account resolution, canonical-account lookup, and original-index tracking so higher layers operate on already-resolved account views.

Structs

FrameInfo

Summary of a safely-parsed loader input frame.

RawAccountIndex

Metadata for one parsed account slot in the loader input.

RawInstructionFrame

Instruction tail discovered after scanning the loader input buffer.

Enums

DirectMappingError

Failure reported by the host/replay SIMD-0449 conformance decoder.

FrameError

Errors returned by the safe parser.

Constants

MAX_SAFE_ACCOUNT_SLOTS

Hard cap on accounts the safe parser will record slot offsets for.

SIMD_0449_TABLE_ENABLED

Whether this build trusts the SIMD-0449 account-pointer table (feature = "simd-0449"). Enabling it before the SIMD activates on the target cluster reads garbage, ship it only alongside the cluster gate, exactly like simd-0321.

Functions

deserialize_accounts^⚠

Deserialize the loader input into AccountViews.

deserialize_accounts_0449^⚠

SIMD-0449 direct account resolution: overlay the runtime’s appended account-pointer table as a borrowed [AccountView], one bounds computation and one from_raw_parts, then capture each account’s invocation-wide resize baseline.

deserialize_accounts_0449_checked^⚠

Validate and consume a SIMD-0449 account-pointer table.

deserialize_accounts_0449_into^⚠

Adapter matching the deserialize_accounts_fast shape: copy up to MAX table entries into the caller’s array (8 bytes per account, a pointer copy, not a record parse) so the existing entrypoint plumbing consumes the table without changing its account storage.

deserialize_accounts_fast^⚠

Fast two-argument deserialize: instruction data and program id are provided directly by the caller (from the SVM’s second entrypoint register), so the walk stops at the last materialized account instead of crossing the rest.

deserialize_leading_accounts^⚠

Materialize at most MAX leading account views without walking to the instruction tail.

loader_account_count^⚠

The number of accounts the loader serialized: the first word of the input buffer. The count-exact entrypoint compares it with the matched arm’s bound before walking anything, so accounts past the bound are refused instead of silently dropped.

parse_instruction_frame_checked

Parse a loader-input byte buffer with full bounds checking.

scan_instruction_frame^⚠

Parse just the instruction tail and account span from the loader input.
