This commit changes the `io::process::Command` API to provide fine-grained control over the environment: * The `env` method now inserts/updates a key/value pair. * The `env_remove` method removes a key from the environment. * The old `env` method, which sets the entire environment in one shot, is renamed to `env_set_all`. It can be used in conjunction with the finer-grained methods. This renaming is a breaking change. To support these new methods, the internal `env` representation for `Command` has been changed to an optional `HashMap` holding owned `CString`s (to support non-utf8 data). The `HashMap` is only materialized if the environment is updated. The implementation does not try hard to avoid allocation, since the cost of launching a process will dwarf any allocation cost. This patch also adds `PartialOrd`, `Eq`, and `Hash` implementations for `CString`. [breaking-change] |
