When a silicon crystal is doped with an n-type conductor on one side and a p-type conductor on the other, a PN junction is formed.
PN junctions are the elementary building blocks of semiconductor devices (diodes, transistors, solar cells, LEDs, and integrated circuits)

Null Pointer Optimization
Rust uses the null pointer optimization (or "niche optimization") for pointer types that can never represent the value 0 (null).

The Mysterious Beauty of Semiconductors
To understand how diodes, transistors, or any integrated circuit work, you must first study the semiconductor – a material that is neither a conductor nor an insulator.

From Rust Source to Executable
The rustc compiler manages a complex, multi-stage process that transforms human-readable Rust source code into highly optimized, machine-executable binaries.
This multi-layered pipeline is fundamental to Rust's core promises: memory safety without GC, high performance, and robust concurrency.
Tokenizationof Source Code- Building an Abstract Syntax Tree (
AST) MacroExpansion and Name Resolution- Transformation to
HIR: Desugaring of syntactic constructions - Providing a
Type System - Converting to
MIR: Generating a Control Flow Graph Borrow Checker- Monomorphization and generation of
LLVM IR - Generation of machine code and
object files Linking: Building the final executable file
Anchor CPI
Cross Program Invocations (CPIs) allow one program to invoke instructions on another program.
