Function decode_psbt 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn decode_psbt(
    network: *const c_char,
    psbt: *const c_char,
) -> *mut c_char

Decodes a PSBT and returns all outputs of the transaction and total size. “miner” is used in the ‘to’ field of an output to indicate fee.

• OUTPUT

  DecodedTx{
    outputs: Vec<DecodedTxIO {
      value: u64,
      to: String,
    }>
  }

Safety

• This function is unsafe because it dereferences and a returns raw pointer.
• ENSURE that result is passed into cstring_free(ptr: *mut c_char) after use.
