#![feature(coverage_attribute)]
|
|
//@ edition: 2021
|
|
|
|
// Demonstrates the interaction of `#[coverage(off)]` and `#[coverage(on)]`
|
|
// in nested functions.
|
|
|
|
// FIXME(#126625): Coverage attributes should apply recursively to nested functions.
|
|
// FIXME(#126626): When an inner (non-closure) function has `#[coverage(off)]`,
|
|
// its lines can still be marked with misleading execution counts from its enclosing
|
|
// function.
