Add new Rust exercises
One of the easiest ways to add new exercises to the Rust track is to translate them from other language tracks on Exercism. This page lists all of the problem specifications in the common pool of exercises which have not yet been implemented in Rust.
The icon links to the language-independent description of the problem.
The icon links to the canonical test data.
We also link to all the implementations of each exercise in other languages, which you can use for inspiration.
Once you've picked an exercise, follow the instructions in this guide and submit your pull request to the Rust track repository on GitHub.
Calculate the date of meetups.
Given a decimal number, convert it to the appropriate sequence of events for a secret handshake.
Take a nested list and return a single list with all values except nil/null
Create a sentence of the form "One for X, one for me."
Given a letter, print a diamond starting with 'A' with the supplied letter at the widest point.
Binary Search Tree
Insert and search for numbers in a binary tree.
Implement basic list operations
Implement the `keep` and `discard` operation on collections. Given a collection and a predicate on the collection's elements, `keep` returns a new collection containing those elements where the predicate is true, while `discard` returns a new collection containing those elements where the predicate is false.
