7 min readTo check if an object is a primitive data type in Rust, you can use the std::mem::size_of function to determine the size of the object in memory. If the size of the object matches one of the known primitive data types (such as i8, i16, i32, i64, u8, u16, u32, u64, f32, f64, bool, char), then it is considered a primitive data type. Alternatively, you can use pattern matching or type inference to verify if the object is a primitive data type.

5 min readIn Elixir, constants can be defined using the defmodule and def syntax. These constants can be used in test modules to make the test code more readable and maintainable. To use constants in Elixir tests, you can define the constants at the top level of the test module using the def keyword. For example, you can define a constant like SOME_CONSTANT = 10 at the top of the test module.You can then use this constant throughout the test module to refer to the value 10.

3 min readInterceptors in Kotlin are powerful tools for handling errors in a more modular and efficient way. By creating an interceptor, you can intercept network requests and responses, providing a centralized point for error handling. To handle errors using interceptor in Kotlin, you can define custom error classes, such as RemoteException, and use them to wrap exceptions thrown during network calls. This allows you to easily distinguish between different types of errors and handle them accordingly.

4 min readIn Rust, there is no built-in function to directly get the current stack frame depth. However, you can achieve this by creating a recursive function that repeatedly calls itself until reaching the base case, thereby measuring the depth of the stack frames. Keep in mind that this method may not be very efficient and could potentially lead to a stack overflow if the depth is too large.[rating:c1abfe4e-5b23-47e2-a608-65097a225475]How can I determine the number of frames on the stack in Rust.

4 min readTo translate a curl command to Elixir using the HTTPoison library, you would first need to install the HTTPoison package in your Elixir project. Then, you can use the HTTPoison functions to send HTTP requests.To translate a simple GET request in curl to HTTPoison, you would use the HTTPoison.get function and pass the URL as an argument. For example, if you have a curl command like: curl http://example.com/api/users You can translate it to Elixir using HTTPoison like this: HTTPoison.

6 min readIn Kotlin, a null value represents the absence of a value in a variable. This can be useful when a variable may not have a value assigned to it at a given time. However, it is important to handle null values properly to prevent null pointer exceptions in your code.To work with null values in Kotlin, you can use nullable types. By appending a "?" to the type of a variable, you are indicating that it can accept null values. For example, if you declare a variable as "String.

7 min readTo write a HTTPS server using Rust, you can use the Hyper crate which is a fast and modern HTTP library for Rust. First, you need to add Hyper to your Cargo.toml file. Then, you can create a new Rust file and start implementing your server logic. You can use the hyper::Server module to create a new HTTPS server instance. You will need to provide a closure that defines the request handling logic.

3 min readIn Elixir, the capture operator (&) is used to capture functions so that they can be passed around as values. This allows functions to be stored in variables, passed as arguments to other functions, or returned as results from other functions. The capture operator simplifies code and makes it easier to work with functions in a functional programming style. It is particularly helpful when working with higher-order functions, such as Enum.map and Enum.

5 min readTo loop over two ArrayLists of different sizes in Kotlin, you can use a loop with an index variable that iterates over the smaller size of the two ArrayLists. Within the loop, you can access elements from both ArrayLists using the index variable. You can also check if you have reached the end of either ArrayList before accessing its element to avoid ArrayIndexOutOfBoundsException.
-
4 min readIn Rust, you can make a thread sleep or wait without using the standard library by using the std::thread::park_timeout function. This function allows you to block a thread for a specified amount of time before resuming its execution. You can also achieve this by creating a custom implementation of a sleep or wait function using low-level synchronization primitives like std::sync::Mutex, std::sync::Condvar, and std::time::Instant.

5 min readIn Elixir, the best way of error handling is using the try and rescue keywords to encapsulate code that may potentially raise an error. By wrapping the code in a try block, you can catch specific types of errors using rescue clauses and handle them accordingly. Additionally, the with keyword can be used for pattern matching on the result of expressions and handling errors in a more elegant and functional way.
