[BUG] Typescript bindings: structs not exported

[rsodre]

Describe the bug
Structs used in contract calls, but not in any models, are not being exported.

To Reproduce

Generate typescript bindings for a contract with a call like this...
(from pistols/dev branch)

// https://github.com/underware-gg/pistols/blob/dev/dojo/src/systems/bank.cairo
use pistols::models::pool::{PoolType, LordsReleaseBill};
#[starknet::interface]
pub trait IBank<TState> {
  // ...
  fn release_lords_from_fame_to_be_burned(ref self: TState, bills: Span<LordsReleaseBill>) -> u128;
  // ...
}

// https://github.com/underware-gg/pistols/blob/dev/dojo/src/systems/tokens/duelist_token.cairo
pub trait IDuelistTokenProtected<TState> {
  // ...
  fn transfer_rewards(ref self: TState, challenge: Challenge, tournament_id: u64, bonus: DuelBonus) -> (RewardValues, RewardValues);
  // ...
}

Expected behaviour
All structs used in system calls should be converted to Typescript.

Having the same issue, for now just created a dummy model that includes the missing Structs.

Have not done this before, but if not urgent would like to take this.

bump!

[cwkang1998]

@rsodre will try to get something out these 2 days, been travelling a bit.

@rsodre attempted to replicate this but can't manage to do it, the branch you pointed to seems to be missing / merged, do you have another example?

[rsodre]

@cwkang1998 you can use this
https://github.com/underware-gg/pistols/tree/3cf4909b0fcbbfb224cf5455da3a8e8817c49312/dojo

start a local katana, cd dojo and ./migrate dev --bindings

on the generated sources, LordsReleaseBill and MockedValue are not present.

this is the latest fix commit I made after generating bindings:
