### Specifying the minimum supported Rust version
Projects that intend to support old versions of Rust can disable lints pertaining to newer features by
specifying the minimum supported Rust version (msrv) in the clippy configuration file.
```toml
msrv = "1.30.0"
```
The msrv can also be specified as an inner attribute, like below.
```rust
#![feature(custom_inner_attributes)]
#![clippy::msrv = "1.30.0"]
fn main() {
...
}
```
Tilde/Caret version requirements(like `^1.0` or `~1.2`) can be specified as well.
Note: `custom_inner_attributes` is an unstable feature so it has to be enabled explicitly.
