manta-cli 2.0.0-beta.66

//! Implements the `manta config show` command.
//!
//! Builds a [`ConfigSummary`] from the merged local settings and,
//! when a session is available, the per-invocation JWT-derived facts
//! (`username`, `name`, `is_admin`, `accessible_groups`) attached to
//! [`crate::common::app_context::AppContext::session`]. The
//! `read_only` flag is sourced from `AppContext::read_only`, not the
//! JWT. Rendering is delegated to [`crate::output::config_summary`].

/// The per-site, server-derived fields (current site, accessible
/// groups, admin/read-only flags) come from `ctx.session` — populated
/// for every authenticated command at the top of
/// [`crate::dispatch::process::process_cli`]. When no site is selected
/// (and therefore no session was built), the renderer prints the
/// local config alone.
///
/// # Errors
///
/// Returns an error only if the renderer fails. The config file path
/// lookup falls back to `"<unknown>"`, individual `Config` lookups use
/// defaults.
