What's inside Sway

Overview of Sway LSP
master
Sway LSP is a language server built on the standardized Language Server Protocol (LSP). It acts as a bridge between Sway source code and your IDE or code editor, providing semantic analysis to enable advanced development features.
Key capabilities include:
- Intelligent code completion
- Precise symbol navigation
- Type information display
- Error detection and semantic analysis

Overview of Sway Standards
master
Sway Standards are usage patterns and API implementations developed to enable cross-compatibility between smart contracts on the Fuel Network. They are categorized into several domains including Native Assets, Predicates, Access Control, and Bridges. For detailed implementation details, developers should refer to the official Sway-Standards Repository.

Overview of the Sway programming language
master
Sway is a statically typed, compiled programming language specifically designed for the FuelVM. It features type inference and traits, aiming to enhance the safety and efficiency of smart contract development through strong static analysis and comprehensive compiler feedback.

Overview of Sway Core
master
Sway Core is the central crate responsible for the core compiler functionality of the Sway language. It serves as the foundation for the Sway compiler ecosystem.

Overview of Sway Intermediate Representation (sway-ir)
master
The sway-ir crate provides a Static Single Assignment (SSA) style Intermediate Representation (IR) for the Sway compiler middle end. It is modeled after LLVM and is designed to facilitate the optimization phase of the compiler pipeline. While currently a work-in-progress and lacking full documentation and optimization passes, it is functional enough to be targeted by Sway for code generation and passes its internal test suite.

What is Forc (Fuel Orchestrator)?
master
Forc (Fuel Orchestrator) is a command-line toolset for developers working within the Fuel ecosystem. It provides essential workflows similar to Rust's cargo, including project scaffolding, code formatting, script execution, contract deployment, and contract testing.

Overview of Forc (Fuel Orchestrator)
master
Forc (Fuel Orchestrator) is a developer toolset for the Fuel ecosystem, providing functionality similar to cargo in the Rust ecosystem. It is used to manage the lifecycle of Sway projects, including scaffolding, formatting, running scripts, deploying contracts, and testing contracts.

Sway toolchain supported operating systems
master
The Sway toolchain supports the following operating systems:
- Linux
- macOS
Note: Windows is currently unsupported.

Use the Sway standard library for storage operations
master
The Sway standard library (sway-lib-std) provides specialized utilities for managing persistent storage. Instead of raw storage manipulation, you can use higher-level abstractions to manage data:
- Mapping: Use this to track and manage key-value pairs in storage.
- Vectors: Use this for persistent, non-heap-allocated collections of items.
- Store & Get: Use these primitives for manual, low-level manipulation of specific storage slots.
For detailed implementation details and usage, refer to the specific documentation for Mapping, Vectors, or Store & Get.

Use Forc (`forc`) to manage Sway projects
master
Forc is the primary entry point for the Fuel toolchain, acting as the 'Fuel Orchestrator' (similar to Rust's Cargo). You use forc to create, build, test, and deploy Sway projects.

Available Asset Operations in Sway
master
Sway provides built-in FuelVM operations to manage the lifecycle of an asset. The core operations are:
- Minting: Creating new assets.
- Burning: Destroying existing assets.
- Transferring: Sending assets from one entity to another.
- Balance Checking: Determining the contract's balance.
