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.
Determine if a word or phrase is an isogram.
Implement a binary search algorithm.
Implement the classic method for composing secret messages called a square code.
Determine if a number is perfect, abundant, or deficient based on Nicomachus' (60 - 120 CE) classification scheme for natural numbers.
Given a string of digits, output all the contiguous substrings of length `n` in that string.
Given a decimal number, convert it to the appropriate sequence of events for a secret handshake.
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.
Binary Search Tree
Insert and search for numbers in a binary tree.
Take a nested list and return a single list with all values except nil/null
Given a diagram, determine which plants each child in the kindergarten class is responsible for.
Implement a doubly linked list
Detect palindrome products in a given range.
Detect saddle points in a matrix.
Correctly determine change to be given using the least number of coins

Given a string representing a matrix of numbers, return the rows and columns of that matrix.
Implement a simple shift cipher like Caesar and a more secure substitution cipher
Simulate a bank account supporting opening/closing, withdraws, and deposits of money. Watch out for concurrent transactions!
Given a letter, print a diamond starting with 'A' with the supplied letter at the widest point.
Output the nursery rhyme 'This is the House that Jack Built'.
Compute the result for a game of Hex / Polygon
Simple Linked List
Write a simple linked list implementation that uses Elements and a List
Take input text and output it transposed.
Output the lyrics to 'The Twelve Days of Christmas'
