< p > When developing programs, we have to solve many problems.
A program can be viewed as a solution to a problem.
It can also be viewed as a collection of solutions to many different problems.
All of these solutions work together to solve a bigger problem.< / p >

< p > There are many problems that share the same form.
Due to the fact that Rust is not object-oriented design patterns vary with respect to other object-oriented programming languages.
While the details are different, since they have the same form they can be solved using the same fundamental methods.< / p >
< p > < a href = "./patterns/index.html" > Design patterns< / a > are methods to solve common problems when writing software.< / p >
< p > < a href = "./anti_patterns/index.html" > Anti-patterns< / a > are methods to solve these same common problems.< / p >
< p > However, while design patterns give us benefits, anti-patterns create more problems.< / p >
< p > < a href = "./idioms/index.html" > Idioms< / a > are guidelines to follow when coding.
They are social norms of the community.
You can break them, but if you do you should have a good reason for it.< / p >
