rustRust struct of any type example
A struct is a custom data type in Rust that allows you to group related data together. It is similar to a class in other languages. Here is an example of a struct that stores information about a person:
struct Person {
name: String,
age: u8
}
This struct has two fields, name and age, both of which are of type String and u8 respectively. The name field stores the person's name as a String and the age field stores the person's age as an u8 (unsigned 8-bit integer).
To create an instance of this struct, we can use the new keyword:
let person = Person {
name: String::from("John"),
age: 30
};
This creates a Person instance with the name John and age 30. We can then access the fields of this instance using dot notation:
println!("Name: {}", person.name);
println!("Age: {}", person.age);
This will print out the following:
Name: John
Age: 30
We can also create methods on our structs to perform operations on the data they contain. For example, we could create a greet method that prints out a greeting for the person:
impl Person {
fn greet(&self) {
println!("Hello, my name is {} and I am {} years old.", self.name, self.age);
}
}
We can then call this method on our person instance:
person.greet();
This will print out the following:
Hello, my name is John and I am 30 years old.
