# `coverage_attribute`
The tracking issue for this feature is: [#84605]
[#84605]: https://github.com/rust-lang/rust/issues/84605
---
The `coverage` attribute can be used to selectively disable coverage
instrumentation in an annotated function. This might be useful to:
- Avoid instrumentation overhead in a performance critical function
- Avoid generating coverage for a function that is not meant to be executed,
but still target 100% coverage for the rest of the program.
## Example
```rust
#![feature(coverage_attribute)]
// `foo()` will get coverage instrumentation (by default)
fn foo() {
// ...
}
#[coverage(off)]
fn bar() {
// ...
}
```
