Struct TychoRouterEncoder 

pub struct TychoRouterEncoder { /* private fields */ }

Encodes solutions to be used by the TychoRouter.

Fields

• chain: Chain to be used
• single_swap_strategy: Encoder for single swaps
• sequential_swap_strategy: Encoder for sequential swaps
• split_swap_strategy: Encoder for split swaps
• router_address: Address of the Tycho router contract
• user_transfer_type: Type of user transfer
• permit2: Optional Permit2 instance for permit transfers
• signer: Optional signer (used only for permit2 and full calldata encoding)

Implementations

impl TychoRouterEncoder

pub fn new( chain: Chain, swap_encoder_registry: SwapEncoderRegistry, router_address: Bytes, user_transfer_type: UserTransferType, signer: Option<PrivateKeySigner>, historical_trade: bool, ) -> Result<Self, EncodingError>

Trait Implementations

impl Clone for TychoRouterEncoder

fn clone(&self) -> TychoRouterEncoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl TychoEncoder for TychoRouterEncoder

fn validate_solution(&self, solution: &Solution) -> Result<(), EncodingError>

Raises an EncodingError if the solution is not considered valid.

A solution is considered valid if all the following conditions are met:

• The solution is not exact out.
• The solution has at least one swap.
• If the solution is wrapping, the given token is the chain’s native token and the first swap’s input is the chain’s wrapped token.
• If the solution is unwrapping, the checked token is the chain’s native token and the last swap’s output is the chain’s wrapped token.
• The token cannot appear more than once in the solution unless it is the first and last token (i.e. a true cyclical swap).

fn encode_solutions( &self, solutions: Vec<Solution>, ) -> Result<Vec<EncodedSolution>, EncodingError>

Encodes a list of Solutions into EncodedSolutions, which include the function signature and internal swap call data.

fn encode_full_calldata( &self, solutions: Vec<Solution>, ) -> Result<Vec<Transaction>, EncodingError>

👎Deprecated: Please use encode_solutions instead

Encodes a list of Solutions directly into executable transactions for the Tycho router.
