The Rust blog

This is the blog of the Rust Programming Language.

It's implemented as a small static site generator, that's deployed to GitHub Pages via Travis.

Building

To build the site locally:

> git clone https://github.com/rust-lang/blog.rust-lang.org
> cd blog.rust-lang.org
> cargo run

You could do it in release mode if you'd like, but it's pretty fast in debug.

From there, the generated HTML will be in a site directory. You can use any web server to check it out in your browser:

> cd site
> python3 -m http.server

The site is now available at http://0.0.0.0:8000.

If you need to preview the site from another machine, pass the host's address via --bind. For example, if running on 192.168.72.73:

> cd site
> python3 -m http.server --bind 192.168.72.73

The site is now available at http://192.168.72.73:8000.

(As a short-cut: If you pass --bind 0.0.0.0, the server will be reachable at all of the host's IP addresses.)

RUST on programming language

The title is a bit confusing to understand the context of the content. In this blog, I am going to run around and see the different aspects of programming language rust. And talk about the concepts that it introduces that are useful for various aspects of programming.

What is Rust?

Simply putting it is a statically as well as strongly typed programming language.

Let me explain:

_statically typed _indicates that all the datatypes that are expressed in the code are known at compile time and memory allocation is done properly.

Image for post

Then what is 👆 that? Let’s just say rust knows what you want to say.

But this doesn’t mean you could declare variables for a complex data type and expect rust to understand. Here comes the next point I mentioned above.

_strongly typed _indicates that the types are designed to make it harder to write syntatically incorrect code.

If you were to do even a little mistake with the syntax or definition of variables then the errors are caught at compile time. Not just the syntax errors but there are various tests build in the compiler to check for unused variablesdead code(Code that will never run), infinite loops as well as the lifetime of variables.

Serde Rust: Serialization Framework for Rust

Serde

*Serde is a framework for serializing and deserializing Rust data structures efficiently and generically.*

You may be looking for:

Serde in action

Click to show Cargo.toml. Run this code in the playground.

[dependencies]

# The core APIs, including the Serialize and Deserialize traits. Always
# required when using Serde. The "derive" feature is only required when
# using #[derive(Serialize, Deserialize)] to make Serde work with structs
# and enums defined in your crate.
serde = { version = "1.0", features = ["derive"] }

# Each data format lives in its own crate; the sample code below uses JSON
# but you may be using a different one.
serde_json = "1.0"

 

use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize, Debug)]
struct Point {
    x: i32,
    y: i32,
}

fn main() {
    let point = Point { x: 1, y: 2 };

    // Convert the Point to a JSON string.
    let serialized = serde_json::to_string(&point).unwrap();

    // Prints serialized = {"x":1,"y":2}
    println!("serialized = {}", serialized);

    // Convert the JSON string back to a Point.
    let deserialized: Point = serde_json::from_str(&serialized).unwrap();

    // Prints deserialized = Point { x: 1, y: 2 }
    println!("deserialized = {:?}", deserialized);
}

Getting help

Serde is one of the most widely used Rust libraries so any place that Rustaceans congregate will be able to help you out. For chat, consider trying the #rust-questions or #rust-beginners channels of the unofficial community Discord (invite: https://discord.gg/rust-lang-community), the #rust-usage or #beginners channels of the official Rust Project Discord (invite: https://discord.gg/rust-lang), or the #general stream in Zulip. For asynchronous, consider the [rust] tag on StackOverflow, the /r/rust subreddit which has a pinned weekly easy questions post, or the Rust Discourse forum. It's acceptable to file a support issue in this repo but they tend not to get as many eyes as any of the above and may get closed without a response after some time.

Introduction to Structured Query Language SQL pdf

SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.

Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:

1. The SQL order standard is genuinely intricate, and it isn’t handy to actualize the whole standard.

2. Every database seller needs an approach to separate its item from others.

Right now, contrasts are noted where fitting.
