Crate bt_rs 

Build tools for Rust.

bt-rs provides helpers for build scripts and tooling that need to inspect the Rust toolchain — starting with parsing rustc --version output into a structured ToolVersion.

Tool-specific APIs live in submodules (e.g. rustc::compiler_version); shared types are re-exported at the crate root.

Installation

Reference in Cargo.toml in the usual way:

bt-rs = { version = "0.1" }

Components

Types

• ToolVersion — major, minor, patch, and build metadata parsed from a tool --version line;
• VersionError — failure to run or parse a tool --version invocation;

Modules

• rustc — rustc compiler version (rustc::compiler_version);

Examples

use bt_rs::rustc::compiler_version;

let version = compiler_version()?;
assert!(version >= (1, 74));
