// vim:fileencoding=utf-8:noet
//! Features powerliners ships beyond the strict 1:1 port of
//! `powerline-status`. Sanctioned non-port location per `docs/PORT.md`.
//!
//! Currently houses:
//!
//! - [`mem_usage`] — 1:1 port of mKaloer's
//! [`powerline_mem_segment`](https://github.com/mKaloer/powerline_mem_segment)
//! plugin (`powerlinemem.mem_usage` Python module). Provides the 4
//! adapter entrypoints the user's theme references by name:
//! - `mem_usage` → `USED/TOTAL` formatted bytes
//! - `mem_usage_percent` → `NN%` of total memory
//! - `mem_swap` → `USED/TOTAL` formatted swap bytes
//! - `mem_swap_percentage` → `NN%` of total swap
//!
//! These names are wired into `ADAPTERS` in
//! `src/bin/shared/render_runtime.rs` so the daemon's segment lookup
//! finds them without a Python `__import__` round-trip.
//!
//! - [`gpu`] — `powerliners.gpu.{gpu_usage_percent,gpu_vram}`
//! (vendor-dispatched: nvidia-smi → rocm-smi → ioreg → intel_gpu_top)
//! - [`disk`] — `powerliners.disk.{disk_usage,disk_usage_percent,disk_io}`
//! - [`thermal`] — `powerliners.thermal.thermal` (CPU/GPU temp + fan RPM)
//! - [`docker`] — `powerliners.docker.containers` (running/total/images
//! via `docker ps` / OCI-compatible CLI)
//! - [`k8s`] — `powerliners.k8s.kubecontext` (current kubectl
//! context + active namespace, honors KUBECONFIG cascade)
//! - [`proc_count`] — `powerliners.proc.process_count` (POSIX `ps -eo
//! stat=` tally by state code: running/sleeping/zombie/dwait/stopped)
//! - [`wthr_extensions`] — IP-based geolocation + on-disk
//! location cache for the weather segment. Upstream powerline takes
//! `location_query` only; these helpers let the segment render
//! without an explicit query and survive transient lookup failures.
//! Imported by `src/ported/segments/common/wthr.rs`.
