Neovim adds vim.async, a structured concurrency library, to its Lua standard library
↗
Neovim has introduced vim.async, a structured concurrency library in its Lua standard library, providing standardized async workflows with cooperative scheduling and parent-child task management.
Plugin authors can now use a built-in async framework instead of relying on third-party libraries or raw Libuv callbacks, reducing dependency collisions and error-prone code. The new model enforces cancellation and error propagation, making asynchronous plugins more predictable and stable. However, adopting vim.async requires learning its task model and may not be compatible with existing plugins that use other coroutine libraries.

vim.async provides a native structured concurrency model in Neovim's Lua standard library.
Tasks run cooperatively via stackful coroutines, with vim.async.await() yielding to the event loop.
Parent-child task relationships enforce cancellation and error propagation, with Task:detach() for independent tasks.
