Quick Overview

Concept

Explanation

Variable

holds data or reference to data

Data type

defines the type of value assigned to a variable. It can be primitive, or non-primitive. Primitives includes, integers, floats, character, boolean, array, tuples and string.

Array

sequence of elements of the same type

Tuple

sequence of elements of different types

Operators

tell the compiler to perform specific operations

Conditional Statements

statements that execute if the associated condition evaluates to true

Loops

blocks of code that keep on executing until a specific condition become true

Functions

a reusable piece of code that is used to perform a set of tasks

Strings

a sequence of character; primitive, i.e., String literal(&str) or non-primitive i.e., String object (String)

Vector

A resizable array

Structs

A composite data type which contains definite values called its variants

Enum

composite data type which contains definite values called its variants

Trait

define an interface for multiple structs

Generics

generalize a data type for struct, enum, trait, function, array and collections

Stack

holds variable having primitive data type (size is known)

Heap

holds variables having non-primitive data type (size is known)

Ownership

defines which variable will hold the value, Primitive data type copy their ownership and non-primitive data move their ownership during assignment

Borrowing

share a variable value or share and mutate a variable value

Lifetime

defines the scope for which the reference is valid
