rust tuple vs vec
In Rust, a tuple is an ordered collection of elements that can have different types. Tuples are defined using parentheses and can store a fixed number of elements. Each element in a tuple can be accessed using dot notation.
On the other hand, a Vec (short for vector) is a dynamic array that can grow or shrink in size. Vectors in Rust are defined using the Vec
Here is an example of creating and using a tuple in Rust:
let my_tuple = (1, "hello", true);
let first_element = my_tuple.0; // accessing the first element
let second_element = my_tuple.1; // accessing the second element
let third_element = my_tuple.2; // accessing the third element
And here is an example of creating and using a vector in Rust:
let mut my_vec: Vec<i32> = Vec::new(); // creating an empty vector
my_vec.push(1); // adding an element to the vector
my_vec.push(2);
my_vec.push(3);
let first_element = my_vec[0]; // accessing the first element
let second_element = my_vec[1]; // accessing the second element
let third_element = my_vec[2]; // accessing the third element
In summary, tuples are fixed-size collections that can hold elements of different types, while vectors are dynamic arrays that can hold multiple elements of the same type and provide additional functionality.
