Struct GpV2OrderStruct 

pub struct GpV2OrderStruct {
    pub sell_token: Address,
    pub buy_token: Address,
    pub receiver: Address,
    pub sell_amount: U256,
    pub buy_amount: U256,
    pub valid_to: u32,
    pub app_data: B256,
    pub fee_amount: U256,
    pub kind: B256,
    pub partially_fillable: bool,
    pub sell_token_balance: B256,
    pub buy_token_balance: B256,
}

Raw on-chain GPv2Order.DataStruct as emitted by the GPv2Settlement contract.

Unlike UnsignedOrder, the kind, sell_token_balance, and buy_token_balance fields are stored as keccak256 hashes rather than typed enums.

Use from_struct_to_order to decode them into a fully typed UnsignedOrder.

Mirrors GPv2Order.DataStruct from the @cowprotocol/composable SDK.

Fields

sell_token: Address

Token to sell.

buy_token: Address

Token to buy.

receiver: Address

Address that receives the bought tokens.

sell_amount: U256

Amount of sell_token to sell (in atoms).

buy_amount: U256

Minimum amount of buy_token to receive (in atoms).

valid_to: u32

Order expiry as a Unix timestamp.

app_data: B256

App-data hash (bytes32).

fee_amount: U256

Protocol fee included in sell_amount (in atoms).

kind: B256

keccak256("sell") or keccak256("buy").

partially_fillable: bool

Whether the order may be partially filled.

sell_token_balance: B256

keccak256("erc20"), keccak256("external"), or keccak256("internal").

buy_token_balance: B256

keccak256("erc20"), keccak256("external"), or keccak256("internal").

Implementations

impl GpV2OrderStruct

pub fn has_custom_receiver(&self) -> bool

Returns true if the receiver is not the zero address.

When receiver == Address::ZERO, the settlement contract uses the order owner as the effective receiver.

Returns

true if receiver is not Address::ZERO, false otherwise.

pub const fn is_partially_fillable(&self) -> bool

Returns true if this order allows partial fills.

Returns

true if partially_fillable is set, false for fill-or-kill orders.

Trait Implementations

impl Clone for GpV2OrderStruct

fn clone(&self) -> GpV2OrderStruct

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpV2OrderStruct

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

Formats the value using the given formatter.

impl Display for GpV2OrderStruct

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

Formats the value using the given formatter.

impl TryFrom<&GpV2OrderStruct> for UnsignedOrder

fn try_from(s: &GpV2OrderStruct) -> Result<Self, Self::Error>

Decode a raw GpV2OrderStruct into a fully typed UnsignedOrder.

Resolves the hashed kind, sell_token_balance, and buy_token_balance fields back into their enum representations via crate::composable::from_struct_to_order.

type Error = CowError

The type returned in the event of a conversion error.
