Struct RuntimeAccount 

#[repr(C)]
pub struct RuntimeAccount {
    pub borrow_state: u8,
    pub is_signer: u8,
    pub is_writable: u8,
    pub executable: u8,
    pub resize_delta: u32,
    pub address: Address,
    pub owner: Address,
    pub lamports: u64,
    pub data_len: u64,
}

Raw C-layout struct matching the Solana BPF account input format.

Each non-duplicate account in the entrypoint input buffer begins with this header, immediately followed by data_len bytes of account data.

The first byte occupies the loader’s duplicate marker slot. Hopper Native reuses that byte as borrow_state, which is valid because canonical accounts enter the program with the 0xFF marker and Hopper uses the same value to mean NOT_BORROWED.

Fields

borrow_state: u8

Borrow tracking state (repurposed from the loader duplicate marker).

Duplicate-account relationships are tracked in raw_input; once a canonical account is identified, this byte becomes Hopper’s borrow state for that canonical record.

is_signer: u8

1 if transaction signer, 0 otherwise.

is_writable: u8

1 if writable, 0 otherwise.

executable: u8

1 if executable, 0 otherwise.

resize_delta: u32

Original account data length, stored in the ABI’s four padding bytes.

The field name is retained for source compatibility with Hopper 0.3.0; it is an immutable resize baseline, not a cumulative delta. Entrypoint parsing initializes it before exposing an AccountView.

address: Address

Account public key (32 bytes).

owner: Address

Owning program (32 bytes).

lamports: u64

Lamport balance.

data_len: u64

Length of account data following this struct.
