# Pollster
Pollster is an incredibly minimal async executor for Rust that lets you block a thread on the result of a future.

```rust
let my_fut = async {};
let result = pollster::block_on(my_fut);
```
That's it. That's all it does. Nothing more. No dependencies, no complexity. No need to pull in 50 crates to evaluate a
future.
Note that `pollster` will not work for *arbitrary* futures because some require a specific runtime or reactor. See
[here](https://rust-lang.github.io/async-book/08_ecosystem/00_chapter.html#determining-ecosystem-compatibility) for more
information about when and where `pollster` may be used. However, if you're already pulling in the required dependencies
to create such a future in the first place, it's likely that you already have a version of `block_on` in your dependency
tree that's designed to poll your future, so use that instead.
