 performance, assuming this is being done infrequently.

 The `TransactionFilter` struct is also available, but requires direct construction of the structs.
 
 ```
-  use transaction_filter::filters::EventFilter;
-
-  let ef = EventFilter {
-      data: Some("spins".into()),
-      struct_type: Some(MoveStructTagFilter {
-          address: Some("0x0077".into()),
-          module: Some("roulette".into()),
-          name: Some("spin".into()),
-      }),
-  };
+use transaction_filter::filters::EventFilter;
+
+let ef = EventFilter {
+  data: Some("spins".into()),
+  struct_type: Some(MoveStructTagFilter {
+    address: Some("0x0077".into()),
+    module: Some("roulette".into()),
+    name: Some("spin".into()),
+  }),
+};
 ```
 
 Once you have some filters built, you can combine them with the boolean operators `and`, `or`, and `not`.
 
 ```
-   let trf = TransactionRootFilterBuilder::default()
-      .success(true).build()?;
-     
-   let utf = UserTransactionFilterBuilder::default()
-      .sender("0x0011".into()).build()?;
-   
-   let ef = EventFilterBuilder::default()
-      .struct_type(
