Usually when generating random numbers it is useful to generate integers within a range, or a p value between 0.0 and 1.0. Whilst modulus operation can be used to reduce the seed to a low integer this uses the low bits, which often go through a short cycle, resulting in a slight skewing of distribut...

// Let's take an arbitrary piece of data, a 4-byte integer in this case let some_data: u32 = 14; // Create a constant raw pointer pointing to the data above let data_ptr: *const u32 = &some_data as *const u32; // Note: creating a raw pointer is totally safe but dereferencing a raw pointe...

// Let's take a mutable piece of data, a 4-byte integer in this case let mut some_data: u32 = 14; // Create a mutable raw pointer pointing to the data above let data_ptr: *mut u32 = &mut some_data as *mut u32; // Note: creating a raw pointer is totally safe but dereferencing a raw pointe...

Unlike normal Rust references, raw pointers are allowed to take null values. use std::ptr; // Create a const NULL pointer let null_ptr: *const u16 = ptr::null(); // Create a mutable NULL pointer let mut_null_ptr: *mut u16 = ptr::null_mut();

Just like in C, Rust raw pointers can point to other raw pointers (which in turn may point to further raw pointers). // Take a regular string slice let planet: &str = "Earth"; // Create a constant pointer pointing to our string slice let planet_ptr: *const &str = &planet ...

Rust has a default formatter for pointer types that can be used for displaying pointers. use std::ptr; // Create some data, a raw pointer pointing to it and a null pointer let data: u32 = 42; let raw_ptr = &data as *const u32; let null_ptr = ptr::null() as *const u32; // the {:p} mappi...

Overloading the addition operator (+) requires implement the std::ops::Add trait. From the documentation, the full definition of the trait is: pub trait Add<RHS = Self> { type Output; fn add(self, rhs: RHS) -> Self::Output; } How does it work? the trait is implemented for...

There are quite a number situations where one has huge amounts of data and using which he has to classify an object in to one of several known classes. Consider the following situations: Banking: When a bank receives a request from a customer for a bankcard, the bank has to decide whether to issue...

malloc() often calls underlying operating system functions to obtain pages of memory. But there is nothing special about the function and it can be implemented in straight C by declaring a large static array and allocating from it (there is a slight difficulty in ensuring correct alignment, in pract...

When run with no arguments, this program starts a TCP socket server that listens for connections to 127.0.0.1 on port 5000. The server handles each connection in a separate thread. When run with the -c argument, this program connects to the server, reads the client list, and prints it out. The clie...

Sometimes we want to use a where query on a a collection of records returned which is not ActiveRecord::Relation.Hence we get the above error as Where clause is know to ActiveRecord and not to Array. There is a precise solution for this by using Joins. EXAMPLE:- Suppose i need to find all user ...

Relational Algebra is not a full-blown SQL language, but rather a way to gain theoretical understanding of relational processing. As such it shouldn't make references to physical entities such as tables, records and fields; it should make references to abstract constructs such as relations, tuples ...
