# `impl_trait_in_bindings`
The tracking issue for this feature is: [#63065]
[#63065]: https://github.com/rust-lang/rust/issues/63065
------------------------
The `impl_trait_in_bindings` feature gate lets you use `impl Trait` syntax in
`let`, `static`, and `const` bindings.
A simple example is:
```rust
#![feature(impl_trait_in_bindings)]
use std::fmt::Debug;
fn main() {
let a: impl Debug + Clone = 42;
let b = a.clone();
println!("{:?}", b); // prints `42`
}
```
Note however that because the types of `a` and `b` are opaque in the above
example, calling inherent methods or methods outside of the specified traits
(e.g., `a.abs()` or `b.abs()`) is not allowed, and yields an error.
