Program Options

Detailed Description

Infrastructure for configuring a seastar application.

The program-options infrastructure allows configuring seastar both by C++ code and by command-line and/or config files. This is achieved by providing a set of self-describing and self-validating value types as well as option groups to allow grouping them into arbitrary tree structures. Seastar modules expose statically declared option structs, which derive from option_group and contain various concrete basic_value members comprising the required configuration. These structs are self-describing, and self-validating, the name of the option group as well as the list of its basic_value member can be queried run-time.
