pub fn install(boot: &mut impl SubsystemBoot)Expand description
Install the plugin-trace views: register plugin-trace-mode + the
:plugin-trace ex-command. Seated in the host’s Phase-B install list (before
the registry freeze), so it registers directly via boot.modes_mut() /
boot.commands_mut().
No dependency on the loader/tracer being installed first: the mode resolves
PluginTracerHandle at activation (by which point boot is complete), and
the ex-command returns a static effect. A missing tracer service at activation
degrades to an empty buffer, never a panic.
