unique

Rust

Copyright (c) 2020 Ronnie Song

This is a Rust based "unique" library crate that find the unique value from an iterator satisfying a predicate.

Usage

Check if 4 is unique in the nums. ```rust use unique::Unique;

let mut nums = vec![]; let num: fn(&&usize) -> bool = |&&n| n == 4;

nums.push(4); assert_eq!(Some(&4), nums.iter().unique(even)); //true ```

Run Example

To run the example program, type the command below:

shell $ cargo run --example example Finished dev [unoptimized + debuginfo] target(s) in 0.04s Running `target/debug/examples/example` None None Some(0) Some(1) None None Some(3) None Some("Ronnie") Some("David") Some("Ronnie") None

Everything went well! It check and find the unique value from an iterator satisfying a predicate without issues, and successfully print results as expected.

Test

To test the library crate, type the command below:

$ cargo test ``` Compiling unique v0.1.0 (/mnt/c/Users/ronsong/Desktop/Docs/Rust Programming/unique) Finished dev [unoptimized + debuginfo] target(s) in 1.71s Running target/debug/deps/test-e7e23989fe7c65fd

running 8 tests test testcases::empty ... ok test testcases::uniqueeven ... ok test testcases::uniqueodd ... ok test testcases::nonuniqueevenorodd ... ok test testcases::uniquenumber ... ok test testcases::nonuniquenumber ... ok test testcases::uniquename ... ok test testcases::nonunique_name ... ok

test result: ok. 8 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out ```

All tests passed with no issues.

The tests are placed in tests/test.rs file that uses std assert_eq!() to test equality of the actual result and expected result of the unique() trait in that file.

Github Action CI is running to do the automated testing. Rust
