feat: Separate encoding swaps from encoding txs
This way the user is responsible for encoding the Tycho Router method inputs that are used as guardrails in execution. Interface changes: - Create EncodedSolution - StrategyEncoder - don't need to know have permit2 or token_in_already_in_router as attributes anymore - encode_strategy returns EncodedSolution now (no method encoding done here now) - TychoEncoder - add encode_solution() method. This is the recommended method for users - needs to have permit2, token_in_already_in_router and router_address as attributes - permit creation is made in the router now Also: - create encoding_utils.rs - update all tests Took 2 hours 42 minutes Took 3 minutes Took 13 minutes

|
||||
/// - `singleSwap`
|

/// - `singleSwapPermit2`
|

/// - `sequentialSwap`
|

/// - `sequentialSwapPermit2`
|

/// - `splitSwap`

/// - `splitSwapPermit2`
|
||||
///
|

/// The encoding includes handling of native asset wrapping/unwrapping, permit2 support,
|
||||
/// and proper input argument formatting based on the selector string.
|
||||
///
|
||||
/// # ⚠️ Important Responsibility Note
|
||||
///
|
||||
/// This function is intended as **an illustrative example only**. **Users must implement
|
||||
/// their own encoding logic** to ensure:
|
||||
/// - Full control of parameters passed to the router.
|
||||
/// - Proper validation and setting of critical inputs such as `minAmountOut`.
|
||||
///
|
||||
/// While Tycho is responsible for encoding the swap paths themselves, the input arguments
|
||||
/// to the router's methods act as **guardrails** for on-chain execution safety.
|
||||
/// Thus, the user must **take responsibility** for ensuring correctness of all input parameters,
|
||||
/// including `minAmountOut`, `receiver`, and permit2 logic.
|
||||
///
|
||||
/// # Min Amount Out
|
||||
///
|
||||
/// The `minAmountOut` calculation used here is just an example.
|
||||
/// You should ideally:
|
||||
/// - Query an external service (e.g., DEX aggregators, oracle, off-chain price feed).
|
||||
/// - Use your own strategy to determine an accurate and safe minimum acceptable output amount.
|
||||
///
|
||||
/// ⚠️ If `minAmountOut` is too low, your swap may be front-run or sandwiched, resulting in loss of
|

/// funds.
|

///
|

/// # Parameters
|

/// - `encoded_solution`: The solution already encoded by Tycho, including selector and swap path.
