What is a configuration file⁉️ A configuration file is a text file that contains various settings and options that control the behavior of a software program or system. The file is usually written in a specific format, such as JSON, YAML,INI, or TOML and is read by the program or system at startup. The settings in the configuration file can be modified to change the behavior of the program or system without having to change the code....
In the previous chapter, we saw we can use slices as references to a contiguous sequence of elements in a collection instead of the whole collection. In this chapter, we will deviate from Ownership rules and see how we can use structs to create custom data types. Structs In Rust, and in object-oriented programming languages, a Struct or structure is a custom data type that lets you hold multiple values in relation to it....
In the previous chapter, we saw how references work in Rust when we do not directly want to transfer ownership. In this chapter, we will see how we can use slices to reference a contiguous sequence of elements in a collection instead of the whole collection. Slices Slices let you reference a contiguous sequence of elements in a collection rather than the whole collection. A slice is a kind of reference, so it does not have ownership....
In the previous chapter, we saw how ownership works in Rust. The main drawback we saw was that for functions, the return value changes ownership and the original variable is no longer usable. In this chapter, we will look at a continuation of ownership, i.e. references. References Instead of passing variables to functions, we can pass references to functions. reference is like a pointer we can follow to get to the data....
In the previous chapter, we saw how we can use data types, functions, and control flow in rust. In this chapter, we will look at the most unique feature of rust - ownership. Ownership Ownership enables Rust to make memory safety guarantees without needing a garbage collector, so it’s important to understand how ownership works. In this chapter, we’ll talk about ownership as well as several related features: borrowing, slices, and how Rust lays data out in memory....
