Enum JsonStorageKey 

pub enum JsonStorageKey {
    Hash(B256),
    Number(U256),
}

A storage key that accepts hex strings up to 32 bytes for eth_getStorageAt and eth_getProof.

A full-width, 32-byte input is stored as Hash and serializes at full width. Shorter inputs are stored as Number and serialize as canonical quantities, so their original prefix, letter case, and leading zeroes are not preserved. Self::as_b256 returns either representation left-padded to 32 bytes.

This distinction mirrors geth’s treatment of eth_getProof storage keys. See how input storageKeys populate the returned StorageResult: https://github.com/ethereum/go-ethereum/blob/00a73fbcce3250b87fc4160f3deddc44390848f4/internal/ethapi/api.go#L658-L690

Variants

Hash(B256)

A full 32-byte key (tried first during deserialization)

Number(U256)

A number (fallback if B256 deserialization fails)

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
