Do we have any sort of tests for this code? cc @michaelwoerister @tromey |
|
Also .. I'm probably not the best reviewer here ... one of you two care to pick this up? |
|
I found I should write test here. https://github.com/rust-lang/rust/blob/4ecf12bf0eb8386626ccdb5f721a7183ccc4eba6/src/test/debuginfo/pretty-std.rs |

@nikomatsakis, I'll take it.
@fukatani, yes, that would be great. I don't know why this test is ignored at the moment. |

@michaelwoerister Could you review this PR? |
|
Thanks a lot, @fukatani! Looks great. I'm wondering though if Also, to make things more consistent with the other collection printers, could you make it |
|
Current PR behavior is the same as #include <set>
int main() {
std::set<int> map;
map.insert(5);
map.insert(6);
return 0;
}I agree that it's a bit redundant. |
|
So far we have not made any effort to match C++'s pretty printers. I'd rather have the Rust pretty printers be consistent among each other. |
|
FWIW the libstdc++ |

pretty print BTreeSet
I want pretty printing for BTreeSet.
```rust
use std::collections::*;
fn main() {
let mut s = BTreeSet::new();
s.insert(5);
s.insert(3);
s.insert(7);
s.remove(&3);
println!("{:?}", s);
}
```
```
(gdb) b 9
(gdb) p s
$1 = BTreeSet<i32> with 2 elements = {[0] = 5, [1] = 7}
```
This is analogy of pretty printing for C++ std::set.
