Module callback 

Thread-local eval context for Rust→Clojure callbacks.

When a native (Rust) builtin needs to call a Clojure function — for example, a comparator passed to sort-by — it can use invoke to do so. The eval context is pushed automatically before every native function call and popped afterward, so invoke is always available inside builtins.

Functions

capture_eval_context

Capture the current eval context so it can be installed on another thread.

install_eval_context

Install a previously captured eval context on the current thread.

invoke

pop_eval_context

Pop the eval context after a native function returns.

push_eval_context

Push the current eval context before calling a native function.

with_eval_context

Call a Clojure-callable Value with the given arguments.
