//! Provides support for language toolchains.
|
|
//!
|
|
//! A language can have associated toolchains,
|
|
//! which is a set of tools used to interact with the projects written in said language.
|
|
//! For example, a Python project can have an associated virtual environment; a Rust project can have a toolchain override.
