//! This is an experimental crate that simplifies the creation of
//! kubectl plugins written using WebAssembly and WASI.
//! These plugins are then ran by [krew-wasm](https://github.com/flavio/krew-wasm).
//!
//! The purpose of this crate is to provide helper functions and structs to
//! perform the following operations:
//! * Determine the Kubernetes API server to connect to
//! * Determine the user identity to be used when interacting with Kubernetes
//! * Simplify the process of performing HTTP requests using the k8s-openapi
//!   crate and the experimental WASI outboung HTTP crate.
