jediswap_v2_swap_router

Router for stateless execution of swaps against JediSwap V2

Functions

exact_input_single

fn exact_input_single(ref self: ContractState, params: ExactInputSingleParams) -> u256

Swaps amount_in of one token for as much as possible of another token

Parameters:

Name	Type	Description
params	ExactInputSingleParams	The parameters necessary for the swap

Return Values:

Type	Description
u256	The amount of the received token

exact_input

fn exact_input(ref self: ContractState, params: ExactInputParams) -> u256

Swaps amount_in of one token for as much as possible of another along the specified path

Parameters:

Name	Type	Description
params	ExactInputParams	The parameters necessary for the multi-hop swap

Return Values:

Type	Description
u256	The amount of the received token

exact_output_single

fn exact_output_single(ref self: ContractState, params: ExactOutputSingleParams) -> u256

Swaps as little as possible of one token for amount_out of another token

Parameters:

Name	Type	Description
params	ExactOutputSingleParams	The parameters necessary for the swap

Return Values:

Type	Description
u256	The amount of the input token

exact_output

fn exact_output(ref self: ContractState, params: ExactOutputParams) -> u256

Swaps as little as possible of one token for amount_out of another along the specified path (reversed) path array will be in format [token_out, token_in, fee] if used for single hop (recommend using exact_output_single) for multihop going from token_in to token_out via token_mid, path will be [token_out, token_mid, fee_out_mid, token_mid, token_in, fee_mid_in]

Parameters:

Name	Type	Description
params	ExactOutputParams	The parameters necessary for the multi-hop swap

Return Values:

Type	Description
u256	The amount of the input token

jediswap_v2_swap_callback

fn jediswap_v2_swap_callback(ref self: ContractState, amount0_delta: i256, amount1_delta: i256, callback_data_span: Span<felt252>)

Parameters:

Name	Type	Description
amount0_delta	i256
amount1_delta	i256
callback_data_span	Span<felt252>
