• Declare store used macros

Define new trait named Module

pub trait Context {
  type Store: bs3::Store;
  type Digest: digest::Digest;

  // Trigger event;
  fn emmit(&mut self, event: impl Event);
  // Spwan a new async work.
  fn spwan<R>(&mut self, handler: impl core::future::Future<Output = R>) -> R;
  // Get block info.
  fn block(&self) -> &Block;
  // Get Consensus info.
  fn consensus(&self) -> &Consensus;
  // Get Governance info.
  fn governance(&self) -> &Governance;
}

pub trait ContextMut: Context {
  fn consensus_mut(&mut self) -> &mut Consensus;
  fn governance_mut(&mut self) -> &mut Governance;
}

When you declare a module:

#[abcf::module]
pub struct MockModule<C: Context> {
  ctx: C,

  #[metadata(
    name = "mock",
    version = 0,
    impl_version,
    target_height = 0,
  )]
  metadata: abcf::Metadata,

  #[storage(merkle="AppendOnlyMerkle")]
  storage_value: Value<u32, C>,

  #[dependence]
  utxo: UtxoModule<C>,
}

When you create a module, please use code like this:

let backend = SledBackend::open_db("target/data/mock");

let mut mock = MockModule::new::<_, Sha3_256>(&backend);

mock.genesis_storage_value(Value::new(123));

let mockv1 = MockModuleV1::new<_, Sha3_256>(&backend);

Currently, we need some work.

Design Document

https://www.notion.so/findora/Modularization-in-Design-263050607c5d4db2b93d0bf8e9109541

Add optimizations for abcf.

TODO

• #30
• Auto declare storage.
• Define merkle algo for special field.
• add module call macros.
• Impl manager's new in trait without in bare code.
• Add Call in macros.
• Extend CallEntry as inner EventBus.
• Add multi-thread support.
• Add returnable support for module call.

Convert the ABCI interface result in Result. And use Result to generate the error log.

Due to the ABCI application will process data in any type, so we need to remove JSON dependence in ABCI.
