- Refactor native extension codes to set rb_data_type_t.wrap_struct_name for each metric and dtype.
- Fix bug that item elements are converted to unsingned integers when dtype is set to float32 (#3).
- Update bundled Annoy version to 1.17.1.
- Refactor config files.
- Refactor codes and configs with RuboCop and clang-format.
- Add
dtype argument to initialize method to specify the data type of vector element.
If you want to load a search index created with the Python bindings, specify 'float32' to the dtype argument.
require 'annoy'
f = 40
t = Annoy::AnnoyIndex.new(n_features: f, metric: 'angular', dtype: 'float32')
t.load('index_with_python_bindings.ann')
- Change the data type of item index from int to int32_t.
- Update type declarations and documentations.
- Introduce conventional commits.
- Remove
-march=native and -DANNOYLIB_MULTITHREADED_BUILD from CXXFLAGS.
For example, the installation command to reproduce the same build as the previous version is as follows:
$ gem install annoy-rb -- --with-cxxflags=-march=native -DANNOYLIB_MULTITHREADED_BUILD
$ bundle config --local build.annoy-rb "--with-cxxflags=-march=native -DANNOYLIB_MULTITHREADED_BUILD"
$ bundle install
- Add dummy constructor call at memory allocation of binding class to prevent occuring segment fault on GC when initialize method is failed.
- Add type declaration file: sig/annoy.rbs
- Fix get_distance method to return integer typed value on hamming metric index.
- Rename native extension files.
- Add GC guard to index saving and loading methods.
- Replace Data_ functions to TypedData_ functions.
- Fix to free char array of error message before calling rb_raise.
- Fix to use array allocated with ruby_xmalloc instead of vector class in C++.
- Update bundled Annoy version to 1.17.0.
- Support multithreaded index building.
