• Improved:

Detail:

Added:

• Added: 5776139d Add #[since(version="1.0")] to specify first version of a feature; by 张炎泼; 2024-04-12

  #[since(version = "1.0.0")] adds a doc line /// Since: Version(1.0.0).

  Example:

  /// Foo function
  ///
  /// Does something.
  #[since(version = "1.0.0")]
  fn foo() {}

  The above code will be transformed into:

  /// Foo function
  ///
  /// Does something.
  ///
  /// Since: Version(1.0.0)
  fn foo() {}

• Added: b172dc8e Add macro expand!() to expand a template; by 张炎泼; 2024-04-13

  expand!() renders a template with arguments multiple times.

  Example:

  expand!(KEYED, // ignore duplicate by `K`
          (K, T, V) => {let K: T = V;},
          (a, u64, 1),
          (a, u32, 2), // duplicate `a` will be ignored
          (c, Vec<u8>, vec![1,2])
  );

  The above code will be transformed into:

  let a: u64 = 1;
  let c: Vec<u8> = vec![1, 2];

Improved:

• Improved: 99596c75 declare_raft_types allows the types in any order; by 张炎泼; 2024-04-13

  By rewriting the template expanding part with a #[proc_macro]
expand!() defined in openraft_macros, declare_raft_types
  does not require the types in fixed order:

  Example:

  declare_raft_types!(All:
          D = (),
          NodeId = u64,
          R = (),
          Node = (),
  

Fixed:

• Fixed: 14d42e4f Load mebmership since last_applied, not last_membership.index on startup; by 张炎泼; 2024-04-25

  Modify StorageHelper::last_membership_in_log() to scan the log
  starting from the last applied index rather than the index of the last
  applied membership log. This change reduces unnecessary I/O operations
  during startup, previously caused by scanning from an incorrect starting
  point.
