Struct Flashloan 

pub struct Flashloan {
    pub loan_amount: String,
    pub liquidity_provider_address: String,
    pub protocol_adapter_address: String,
    pub receiver_address: String,
    pub token_address: String,
}

Flash loan metadata.

Embedded in Metadata when the order uses a flash loan for execution. Records the loan amount, liquidity provider, protocol adapter, receiver, and token address so the settlement contract and solvers can reconstruct the flash-loan flow.

Example

use cow_app_data::types::Flashloan;

let fl = Flashloan::new(
    "1000000000000000000", // 1 ETH in wei
    "0xLiquidityProvider",
    "0xTokenAddress",
)
.with_protocol_adapter("0xAdapterAddress")
.with_receiver("0xReceiverAddress");

Fields

loan_amount: String

Loan amount in token atoms (decimal string).

liquidity_provider_address: String

Address of the liquidity provider.

protocol_adapter_address: String

Address of the protocol adapter contract.

receiver_address: String

Address that receives the flash loan proceeds.

token_address: String

Address of the token being flash-loaned.

Implementations

impl Flashloan

pub fn new( loan_amount: impl Into<String>, liquidity_provider_address: impl Into<String>, token_address: impl Into<String>, ) -> Self

Construct a Flashloan record with the core required fields.

protocol_adapter_address and receiver_address default to empty strings; set them via with_protocol_adapter and with_receiver.

Parameters

• loan_amount — the flash-loan amount in token atoms (decimal string, e.g. "1000000000000000000" for 1 ETH).
• liquidity_provider_address — 0x-prefixed address of the liquidity pool providing the flash loan.
• token_address — 0x-prefixed address of the token being flash-loaned.

Returns

A new Flashloan with adapter and receiver addresses empty.

Example

use cow_app_data::types::Flashloan;

let fl = Flashloan::new("1000000000000000000", "0xPool", "0xToken")
    .with_protocol_adapter("0xAdapter")
    .with_receiver("0xReceiver");
assert_eq!(fl.loan_amount, "1000000000000000000");
assert_eq!(fl.protocol_adapter_address, "0xAdapter");

pub fn with_protocol_adapter(self, address: impl Into<String>) -> Self

Set the protocol adapter contract address.

The adapter contract mediates between the settlement contract and the flash-loan liquidity provider.

Parameters

• address — 0x-prefixed Ethereum address.

Returns

self with protocol_adapter_address set.

pub fn with_receiver(self, address: impl Into<String>) -> Self

Set the receiver address for flash loan proceeds.

Parameters

• address — 0x-prefixed Ethereum address that receives the borrowed tokens.

Returns

self with receiver_address set.
