Liquidation

Encode ContractPrice

Name	Rule
pariId	1 byte
marketPrice	15 bytes, encode in big endian, then pass to the pad_front function in Rsut SDK

Encode OrderPriceInfo

Name	Rule
tokenId	2 byte, change to u16, then encode in big endian
marketPrice	15 bytes, encode in big endian, then pass to thepad_front function in Rust SDK

Encode Liquidation

Name	Rule
type	1 byte, 0x0d
accountId	4 bytes
subAccountId	1 byte
accountIdNonce	4 bytes
oraclePrices	31 bytes
liquidationAccountId	4 bytes
fee	2 bytes, refer to fee pack method in BigUint pack algorithm
feeToken	2 bytes

49 bytes in total, where the oraclePrices encode process is as blew:

• Encode the oraclePrices into a bytes list in order;

• Pass the bytes list to the SDK rescue_hash function then get the 31 bytes result.
