# `compile_error`
|
||||||
|
|
||||||
|
The tracking issue for this feature is: [#40872]
|
||||||
|
|
||||||
|
[#29599]: https://github.com/rust-lang/rust/issues/40872
|
||||||
|
|
||||||
|
------------------------
|
||||||
|
|
||||||
|
The `compile_error` feature adds a macro which will generate a compilation
|
||||||
|
error with the specified error message.
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
```rust
|
||||||
|
#![feature(compile_error)]
|
||||||
|
|
||||||
|
fn main() {
|
||||||
|
compile_error!("The error message"); //ERROR The error message
|
||||||
|
}
