๐ฃ Rust Interview Deep Dive ๐ฆ๐
A repository for systematic preparation for Rust interviews at the middle, senior, and staff levels. ๐ผ๐
Inside 100 real questions from interviews in product and infrastructure companies, detailed analyses with code examples and scenarios of tasks that occur in production. ๐ป๐๏ธ Not "guess the program's output", but the mechanics on which real services are built. ๐ ๏ธ๐
Here are lock-free structures, self-referential types in async, FFI with tensor libraries, correct Send on guards via await, memory ordering under loom, soundness of custom collections. ๐โก And it all starts with the basics. Ownership, borrowing, lifetimes. ๐งฑ๐ Those who want can start from scratch or at the staff level. ๐ถโโ๏ธ๐จโ๐ป

The
:= operator is called the "walrus" because the symbols resemble the eyes and tusks of a walrus ๐ฆญIt was introduced in Python 3.8 and allows you to assign a value to a variable and use it directly within the expression at the same time.
For example:
while (line := input("Say something: ")) != "quit":
print(f"You said: {line}")Without it, you would have to retrieve the value separately using
input(), and then check it.Have you ever used the

Understanding algorithms changes the way you write code. ๐ง This playlist teaches you exactly that: understanding.
Pavel Mavrin. 61 lectures. Free. ๐
Here's the difference:
Before understanding algorithms:
- You use hash tables for everything.
- You write the code first, then optimize it.
- You estimate the time complexity randomly.
After:
- You choose the appropriate data structure for the task.
- You think about complexity before writing the code.
- You learn an approach that is suitable for solving the problem.
What you will learn:
โ Time complexity and sorting.
โ Dynamic programming.
โ Advanced trees: segment tree, Fenwick tree, splay tree, link-cut tree.
โ Graph algorithms: traversals, shortest paths, flows.
โ String algorithms: substring search, suffix structures.
โ Fast Fourier Transform, linear programming, cryptography.
