adapters.rs

1//! The native agent CLIs SCV can delegate to, one descriptor each.
2//!
3//! A descriptor is the whole integration: the default command line, where the
4//! CLI keeps its state inside SCV's private agent home, which inherited
5//! variables it must never see, and how `scv agents login|status|logout`
6//! handle it. Adding an agent means adding one entry to [`ADAPTERS`].
