Overview

A class to get information about the Rust toolchains, and how they map to Ruby platforms.

Examples:

RbSys::ToolchainInfo.new("x86_64-unknown-linux-gnu").ruby_platform # => "x86_64-linux"
RbSys::ToolchainInfo.new("x86_64-unknown-linux-gnu").supported? # => true
RbSys::ToolchainInfo.new("x86_64-unknown-linux-gnu")
