Pretty exciting to see this potential support coming soon 🙏 Thanks @zemse

It is so version specific that it requires ethers@6.0.0-beta-exports.10

[zemse]

typechain-target-ethers-v6@0.0.2 is published with this fix.

[stevealexrs]

How do I provide structs as function input? The generated struct is declared like this:

export declare namespace ContractName {
  export type SignatureStruct = {
    signer: AddressLike;
    v: BigNumberish;
    r: BytesLike;
    s: BytesLike;
  };
}

using import { type ContractName } from 'path' doesn't work

EDIT: It is fine, I got the syntax mix up. 😳 I should cast it as interface instead of init it like an object, ie { } as Structure instead of Structure {}.

[zemse]

That should be import type { ContractName } from 'path', notice "type" is outside of the {}. Or if that was a typo can you describe more about the error you are facing?

// example
import type { ISwapRouter } from '../typechain';
const input: ISwapRouter.ExactInputParamsStruct = {
  path: '0x1234',
  recipient: '0x000',
  deadline: 1,
  amountIn: 1,
  amountOutMinimum: 1,
};
