Description
If I run the following code :
use std::collections::BinaryHeap;
#[derive(Debug)]
pub struct MyStruct
{
bh: BinaryHeap<i32>,
}
fn main() {
let m = MyStruct {
bh: BinaryHeap::new(),
};
}
I get the following error :
test.rs:6:2: 6:21 error: the trait `core::fmt::Debug` is not implemented for the type `collections::binary_heap::BinaryHeap<i32>` [E0277]
test.rs:6 bh: BinaryHeap<i32>,
^~~~~~~~~~~~~~~~~~~~~~~
test.rs:3:10: 3:15 note: in expansion of #[derive_Debug]
test.rs:3:10: 3:15 note: expansion site
test.rs:6:2: 6:21 note: `collections::binary_heap::BinaryHeap<i32>` cannot be formatted using `:?`; if it is defined in your crate, add `#[derive(Debug)]` or manually implement it
test.rs:6 bh: BinaryHeap<i32>,
^~~~~~~~~~~~~~~~~~~~~~~
test.rs:3:10: 3:15 note: in expansion of #[derive_Debug]
test.rs:3:10: 3:15 note: expansion site
error: aborting due to previous error
I don't see any reason for the trait Debug not to be implemented for BinaryHeap. If seeing the nodes of it is a problem, at least a ByanryHeap[size: x]
could be enough.
