What is decoder or encoder for string data type ?

[aryaadinulfadlan]

I didn't find method for decoding / encoding string data type, how to decode / encode a string ?
I got this boilerplate from create-solana-dapp template https://github.dev/solana-foundation/templates/tree/main/gill/gill-next-tailwind-basic

export type InitializePoolInstructionData = { 
  discriminator: ReadonlyUint8Array;
  pool_id: number;
  pool_description: string;
};

export function getInitializePoolInstructionDataDecoder(): FixedSizeDecoder<InitializePoolInstructionData> {
  return getStructDecoder([
    ['discriminator', fixDecoderSize(getBytesDecoder(), 8)],
    ['pool_id', getU32Decoder()],
    ['pool_description', ???],
  ]);
}

I thought there was a method called getStringDecoder()
What do you think ?

are you using codama?

Yes, I’m using Codama.
Sorry, I forgot to update this topic. it’s basically been solved.
It turns out the code was already generated by Codama.

Thanks a lot for your attention!
