Vector2d Library

The following library is created for handling the vector for the animation library where we put our engine. The libray has several modules and support

Changelog

• 2023-07-13 20:32:
  • vectorlib is ready to be deployed.

• 2023-07-12 22:53:

  • Now the implementation work for both .add() method and the operators for all the given operations (addition, subtractions, multiplication, division)

• 2023-07-12 23:22:

  • Finished adding the verboseVectors which will let us know when the vector gets dropped from the memeory (useful for debugging purposes).
  • Implementing the test for all assocaited methods.
• 2023-07-10 21:36:30:
  • Create the struct for the vectorlib
  • Support testing for unit test and library documentation test.
  • Imported to the Engine crate for our animation platform.

Notes

• 2023-07-12 22:24:

  • For the verboseVectors I have used the composition of and built on top of the vector2d. This was necessary since I cannot add a nother field called verbose for the struct of Vector2d (stand Add, Sub, Div and Mul needs only two fields).
  • For implementing the std::fmt::Display for the verboseVectors, I found a creative way to extract first the Some(vector) since Option is not implementing for the Display trait, check the std::fmt::Display trait at the end of the verbose_vector2d_module.rs module.

• 2023-07-10 22:49:26:

  • Up to this point the Vector2d supports
    • (+,-,*,/) operators for the vector
      • Input can be vector or scalar
    • .add(), .div(), .mul() and .sub() accepts only Vector2d cannot accept scalar
      • Meaning that let s = v.div(8.0) will not work.

Features

• [x] Generic format for the vector
• [x] Logging and error handling, checkvectorResult for example.
• [x] Support traits for display in debugging mode.
• [x] Operators overloading for (+)/(-)/(/)/(*) for our vector.
• [ ] Adding support for other vector methods - in progress
  • [x] lerp function.
  • [x] distance between two vectors.
  • [x] cross product similar to the dot product.
  • [x] negate
  • [x] zero vector initalizer.
  • [x] ones vector initalizer.

Welcome message

• You can run the command, for lunching the src/main.rs which is not necessary, but I created for demostration purposes.

```sh cargo run --quiet

or

cargo run -j 10 --quiet ```

Testing Module

• Using the testing command below will run the test/tests.rs script along side with the documentation scripts for each metho in the vectorlib::math::vector_module::Vector2d of Vector2d strcut methods.

sh cargo test - Sometimes we want to see the results output of some selected variables by the specified test. To see the printed values during cargo test, you can use the --nocapture flag. This flag prevents the test framework from capturing the output, allowing the printed values to be displayed in the console.

```sh cargo test -- --nocapture

Or

cargo test -j 8 -- --nocapture ```
