Add Rust embedding examples and tidy examples/ - #120
Merged
Conversation
Frees the top-level examples/ directory for Rust embedding examples that show what the API actually looks like. Drop fib-tail.lisp; the existing fib.lisp + fib-fast.lisp + tail-recursion.lisp already cover naive recursive, iterative, and TCO-flavoured demos.
The smallest possible embedding sketch: register a Rust function, evaluate a Lisp program that calls both it and a built-in, and read the result back into Rust.
Shows the AsPlist! macro deriving keyword-argument conversion for a Rust struct (with renamed and optional fields) and a defun that takes a Plist<T> directly. Three call sites cover the default / override / partial-override shapes.
Demonstrates the three host-side dispatch helpers — ctx.funcall on a named symbol, ctx.map over a list with a (lambda ...) value, and ctx.reduce for an aggregation. Together they cover the common case of running user-supplied Lisp against host-owned data.
A `Color` struct lives in Lisp as a black-box `TulispAny` value wrapped by `Shared`. Rust-defined `defun`s construct and inspect it; Lisp ferries the value through `let` and `list` without peeking inside. The pattern fits host applications that own complex state (connections, handles, domain models) and only expose typed operations to user-supplied Lisp.
Navigational index for the examples directory: a table per category (Rust embedding vs. Lisp scripts) with one-line descriptions and the exact cargo invocation. First place a new embedder is likely to look once they clone the repo.
