Function

DrySwap


              func DrySwap(
	token0Path string,
	token1Path string,
	fee uint32,
	zeroForOne bool,
	amountSpecified string,
	sqrtPriceLimitX96 string,
) (string, string, error)

DrySwap simulates a swap without executing it, returning the expected output.

This is a read-only operation that does not modify pool state. Used by router for multi-hop swap simulations and by clients for price quotes.

Parameters:

token0Path: Path of the first token in the pool pair.
token1Path: Path of the second token in the pool pair.
fee: Fee tier identifying the pool.
zeroForOne: True to sell token0 for token1; false to sell token1 for token0.
amountSpecified: Decimal signed amount; positive requests exact input and negative requests exact output.
sqrtPriceLimitX96: Price boundary in Q64.96 fixed-point form at which the simulation must stop.

Returns:

amount0: Simulated signed token0 delta, as a decimal string; "0" on an unsuccessful simulation.
amount1: Simulated signed token1 delta, as a decimal string; "0" on an unsuccessful simulation.
error: Nil when the simulation succeeds; non-nil when validation, computation, or pool-balance checks fail.

Command
