what is "use" keyword

const baseProcedure = t.procedure
  .input(z.object({ townName: z.string() }))
  .use((opts) => {
    const input = opts.input;
           
const input: {
    townName: string;
}
 
    console.log(`Handling request with user from: ${input.townName}`);
 
    return opts.next();
  });

const baseProcedure = t.procedure
  .input(z.object({ townName: z.string() }))
  .use((opts) => {
    const input = opts.input;
           
const input: {
    townName: string;
}
 
    console.log(`Handling request with user from: ${input.townName}`);
 
    return opts.next();

where does opts.path and opts.type came from ? i guess by default it only stores ctx ,next and input

const loggerMiddleware = middleware(async (opts) => {
  const start = Date.now();
 
  const result = await opts.next();
 
  const durationMs = Date.now() - start;
  const meta = { path: opts.path, type: opts.type, durationMs };
 
  result.ok
    ? console.log('OK request timing:', meta)
    : console.error('Non-OK request timing', meta);
 
  return result;
});
 
export const loggedProcedure = publicProcedure.use(loggerMiddleware);

const loggerMiddleware = middleware(async (opts) => {
  const start = Date.now();
 
  const result = await opts.next();
 
  const durationMs = Date.now() - start;
  const meta = { path: opts.path, type: opts.type, durationMs };
 
  result.ok
    ? console.log('OK request timing:', meta)
    : console.error('Non-OK request timing', meta);
 
  return result;
});
 
export const loggedProcedure = publicProcedure.use(loggerMiddleware);

the code is from middleware documentation

i never knew if one can pass arguments to the next() function , my doubt is why are we passing them and how do we use them

opts object passed to mutation , i can not understand where it came from

export const authorizedProcedure = publicProcedure
  .input(z.object({ townName: z.string() }))
  .use((opts) => {
    if (opts.input.townName !== 'Pucklechurch') {
      throw new TRPCError({
        code: 'FORBIDDEN',
        message: "We don't take kindly to out-of-town folk",
      });
    }
 
    return opts.next();
  });
 
export const appRouter = t.router({
  hello: authorizedProcedure.query(() => {
    return {
      message: 'hello world',
    };
  }),
  goodbye: authorizedProcedure.mutation(async (opts) => {
    await opts.ctx.signGuestBook();
 
    return {
      message: 'goodbye!',
    };
  }),
});

export const authorizedProcedure = publicProcedure
  .input(z.object({ townName: z.string() }))
  .use((opts) => {
    if (opts.input.townName !== 'Pucklechurch') {
      throw new TRPCError({
        code: 'FORBIDDEN',
        message: "We don't take kindly to out-of-town folk",
      });
    }
 
    return opts.next();
  });
 
export const appRouter = t.router({
  hello: authorizedProcedure.query(() => {
    return {
      message: 'hello world',
    };
  }),
  goodbye: authorizedProcedure.mutation(async (opts) => {
    await opts.ctx.signGuestBook();
 
    return {
      message: 'goodbye!',
    };
  }),
});

here in goodbye route , where does the opts object come from , in authorized proccesor middleware , i get it otps come from the input but in goodbye i am not able to understand where opts come from , maybe

  return opts.next();

  return opts.next();

passes it to the goodbye route
