Enum Stability Copy item path Source pub enum Stability {
Experimental,
Preview,
Stable,
}Expand description A node in the command tree.
Maturity tier a command can declare, governing whether it is offered during
tab-completion. Ordered least-to-most stable, so the derived Ord reads as
“at least this stable”: a command is suggested when its stability >= the
active CommandTree::min_stability threshold.
Commands default to Stability::Stable . The completion threshold defaults
to Stability::Preview , so Experimental commands are hidden from
suggestions until the threshold is lowered (e.g. a leading ---experimental
on the line). Stability only governs what completion suggests — every
command remains runnable regardless of its tier.
Early / unstable. Hidden from completion unless the threshold is lowered.
Available for preview. Shown at the default threshold.
Production-ready. The default for any command that doesn’t declare one.
Parse a stability name (case-insensitive): stable, preview, or
experimental. None for anything else.
The lowercase canonical name.

Tests for !=. The default implementation is almost always sufficient,
and should not be overridden without very good reason.
