target.rs

1//! This module defines the structures and logic for handling target-specific configuration
2//! within the `bootstrap.toml` file. This allows you to customize build settings, tools,
3//! and flags for individual compilation targets.
4//!
5//! It includes:
6//!
7//! * [`TomlTarget`]: This struct directly mirrors the `[target.<triple>]` sections in your
8//!   `bootstrap.toml`. It's used for deserializing raw TOML data for a specific target.
9//! * [`Target`]: This struct represents the processed and validated configuration for a
10//!   build target, which is is stored in the main `Config` structure.
