Summary of Changes

Breaking Changes

As a rule of thumb, any items not tagged #[wasm_bindgen] are moved to onc and some that are tagged, are partially separated. Here are some of the items that is affected:

1. wasm_rs::phonotactic::Phonotactic is now split into two: the original and onc::phonotactic::PhonotactilRule. Logic functions are deferred to PhonotacticRule and can be easily accessed by Phonotactic.as_rule().

2. Phrase is moved to onc crate as is. No APIs are found broken.

3. SyllableUnit is moved to onc crate as is. No APIs are found broken.

4. SyllableTag is moved to onc crate as is. No APIs are found broken.

5. AltTagVec is moved to onc crate as is. No APIs are found broken.

6. wasm_rs::phonotactic::InnerParseResult<'a> becomes onc::ParseResult<'a>.
   a. Consequently, InnerParseResult.render(string) has now become wasm_rs::phonotactic::ParseResult.from_inner() because of visibility hierarchy (onc::ParseResult now cannot see wasm_rs::phonotactic::ParseResult). This changes the API from before:

   // Before
   InnerParseResult::from(s).render(options)
   
   // After
   use onc::ParseResult as InnerParseResult;
   ParseResult::from_inner(&InnerParseResult::from(s), &options)

7. wasm_rs::imbuhan::Imbuhan { ... } struct becomes a newtype wasm_rs::imbuhan::Imbuhan(onc::affixes::AffixesRule<JenisKata>) with the original fields deferred to AffixesRule<POS> and the method names are put as is but the logic is pushed to the inner struct like so:

   // Before
   struct Imbuhan {
       untuk: HashSet<JenisKata>,
       awal: Option<String>,
       akhir: Option<String>,
       ganti: Option<Ganti>
   }
   impl Imbuhan {
       pub fn transform_string_with(&self, input: &str, phonotactic: &PhonotacticRule) -> String;
   }

   // After
   // File: onc::affixes.rs
   struct AffixesRule<POS: Hash + Eq> {
       untuk: HashSet<POS>,
       awal: Option<String>,
       akhir: Option<String>,
       ganti: Option<Ganti>
   }
   impl<POS: Hash + Eq> AffixesRule<POS> {
       pub fn transform_string_with(&self, input: &str, phonotactic: &PhonotacticRule) -> String;
   }
   // File: src::imbuhan.rs
   use onc::affixes::AffixesRule
   struct Imbuhan(AffixesRule<JenisKata>)
   impl Imbuhan {
       pub fn transform_string_with(&self, input: &str, phonotactic: &PhonotacticRule) -> String {
       self.0.transform_string_with(input, phonotactic)
       }
   }

Quality of Life

1. Add two examples to wasm_rs: phonotactic.rs and imbuhan.rs showing how the frontend is expected to use the interface.
2. Tests are moved to onc
