Struct StorageProgram 

pub struct StorageProgram {
    pub target: Address,
    pub code: Bytes,
    pub calldata: Bytes,
}

A caller-supplied extraction program: arbitrary bytecode injected at target through a code override and executed by one eth_call.

The slot-list extractor requires the client to know every slot key up front. A custom program removes that constraint — it can derive what to read inside the EVM. Example: a Uniswap V3 loader that walks the tickBitmap words on-chain and returns every initialized tick’s data in a single round trip, with no calldata at all (the two-phase bitmap-then-ticks pattern collapsed into one call). The program runs at the target’s address, so SLOAD reads the target’s real storage; the output format is whatever the program returns — decoding is the caller’s contract with its own bytecode.

See examples/bulk_storage_bench.rs for a worked program (a one-shot Uniswap V3 observation-ring loader that reads the cardinality from slot0 and returns the whole ring) and the offline revm tests in tests/bulk_storage.rs that execute it.

Fields

target: Address

Address whose storage the program reads (its code is replaced by code for the duration of the call).

code: Bytes

Runtime bytecode to inject at target.

calldata: Bytes

Calldata passed to the program (may be empty).

Trait Implementations

impl Clone for StorageProgram

fn clone(&self) -> StorageProgram

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StorageProgram

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for StorageProgram

impl PartialEq for StorageProgram

fn eq(&self, other: &StorageProgram) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
