In r-lib/external: Isolate Functions for Remote Execution

carrier (development version)

• crate() gains a .parent_env argument. The default is baseenv() in order to isolate the crate from the global search path. You can now set it to another environment. For instance, set it to globalenv() to make your crate inherit from the search path. Note that, as the global environment is serialized by name rather than by value, the crate is still isolated from objects in the global environment (#16).

• crate() now requires all ... arguments to be named instead of silently dropping unnamed arguments (#15).

carrier 0.1.1

• Crated functions no longer carry source references (#6).

• Fixed issue that prevented crate sizes to be printed in human-readable format (r-lib/lobstr#60).

carrier 0.1.0

Initial release. The package currently only contains a single method for creating crates that requires users to be explicit about what data to pack in the crate. A future release will provide a method to figure out automatically what objects the crate depends on (with inevitable false positives and negatives).
