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.

Structs

EvalContextGuard

RAII guard that pops one eval context on drop (including on unwind).

Functions

capture_eval_context

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

current_is_async

True when the innermost active eval context is inside an ^:async function body. Returns false when there is no active context.

install_eval_context

Install a previously captured eval context on the current thread.

install_eval_context_guard

Like install_eval_context, but returns a guard that pops the context when dropped.

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.
