Rustup
rustup is a programming language toolchain manager that automates the installation, versioning, and configuration of the Rust compiler and its associated build tools. It serves as a toolchain installer and version manager, enabling the deployment of the language ecosystem across different operating systems.
The system manages multiple compiler versions across stable, beta, and nightly release channels, allowing users to switch between these versions to meet different environment requirements. It also functions as a cross-compilation manager by installing pre-compiled standard libraries to build binaries for various target architectures and operating systems.
The project provides capabilities for toolchain installation, release channel management, and environment maintenance. These workflows ensure that the compiler and its components are kept current through regular updates.
Features
- Toolchain Managers - Automates the downloading and setup of the programming language and toolchain across different operating systems.
- Compiler Version Managers - Automates the installation and switching of different Rust compiler versions and release channels.
- Language-Specific Toolchain Orchestrators - Manages specific toolchains, environment profiles, and compilation targets for the Rust language.
- Cross-Architecture Binary Compilation - Compiles software into executable binaries for multiple target hardware architectures.
- Cross-Compilation Tooling - Provides tooling and workflows for building binaries for different target platforms and architectures.
- Toolchain Versioning - Organizes multiple compiler versions from different release channels to keep the environment current.
- Shim-Based Dispatch - Uses shim binaries to intercept compiler calls and redirect them to the currently active toolchain.
- Runtime Version Switching - Enables toggling the active compiler version between stable, beta, and nightly releases.
- Manifest-Driven Installations - Uses remote JSON manifests to determine the required binary versions and checksums for toolchain installation.
- Multi-Version Compiler Management - Manages multiple compiler versions across stable, beta, and nightly release channels.
- Channel-to-Version Mapping - Resolves release channel labels like stable, beta, and nightly to specific compiler version strings.
- Cross-Compilation Managers - Installs pre-compiled standard libraries to enable building Rust binaries for various target architectures.
- Rust-Implemented Tooling - Provides a high-performance tool implemented in Rust for installing and updating the compiler toolchain.
- Cross-Platform Binary Generation - Generates executable binaries for diverse CPU architectures and operating systems using pre-compiled standard libraries.
- Toolchain Installers - Provides a command-line tool to download and set up the Rust programming language and core components.
- Isolated Runtime Directories - Stores multiple compiler versions in separate filesystem paths to prevent conflicts and allow side-by-side installations.
- Binary Distributions - Provides pre-compiled binaries mapped to host and target triples for efficient cross-platform deployment.
- Local Environment Maintenance - Maintains the local development environment by updating the compiler and associated toolchain components.
- Release Channel Management - Organizes compiler updates into stable, beta, and nightly channels to control version delivery.
- Atomic Installation Swaps - Implements atomic installation swaps by preparing new components in temporary directories before replacing active ones.
- Developer Tools - Official Rust toolchain installer.
- Development Tools - Official installer for managing Rust toolchains.
