The Java String contains function is a method that is used to check whether a particular sequence of characters is present in a given string or not. It returns a boolean value of true if the specified sequence of characters is found in the string, and false otherwise. The method takes a single argument, which is the sequence of characters to be searched for in the string. It is case-sensitive, meaning that it will only match the exact sequence of characters provided. The contains function is commonly used in string manipulation and searching operations in Java programming. Keep reading below to learn how to Java String contains in Rust.

Java String contains in Rust With Example Code
Java String contains is a method that checks if a string contains a specified sequence of characters. In Rust, we can achieve the same functionality using the contains method provided by the Rust standard library.
To use the contains method, we first need to convert our string to a Rust String type. We can do this using the from method provided by the Rust String type. Once we have our string in the correct format, we can call the contains method to check if it contains the specified sequence of characters.
Here’s an example code snippet that demonstrates how to use the contains method in Rust:
let my_string = String::from("Hello, world!");
let contains_world = my_string.contains("world");
println!("Does my_string contain 'world'? {}", contains_world);
In this example, we create a new Rust String called my_string and initialize it with the value “Hello, world!”. We then call the contains method on my_string with the argument “world” to check if it contains the sequence of characters “world”. Finally, we print the result of the contains method using the println! macro.
Using the contains method in Rust is a simple and efficient way to check if a string contains a specified sequence of characters.
Equivalent of Java String contains in Rust
In conclusion, Rust provides a powerful and efficient way to check if a string contains a specific substring. The equivalent function to Java’s String contains() method in Rust is the contains() method of the Rust String type. This method returns a boolean value indicating whether the string contains the specified substring or not. The Rust language is gaining popularity among developers due to its performance, safety, and concurrency features. With Rust, developers can write high-performance code without sacrificing safety and security. The String type in Rust is a great example of how Rust provides a safe and efficient way to work with strings. In summary, if you are a Java developer looking to switch to Rust, you can rest assured that Rust provides an equivalent function to Java’s String contains() method. The Rust contains() method is easy to use and provides efficient substring searching capabilities.
