### Use DHAT to profile heap allocations
|
||||
|
||||
If you are not only interested in the runtime of your solution, but also its memory allocation profile, you can use the template's [DHAT](https://valgrind.org/docs/manual/dh-manual.html) integration to analyze it. In order to activate DHAT, call the `solve` command with the `--dhat` flag.
|
||||
|
||||
```sh
|
||||
cargo solve 1 --dhat
|
||||
|
||||
# output:
|
||||
# Running `target/dhat/1`
|
||||
# dhat: Total: 276 bytes in 3 blocks
|
||||
# dhat: At t-gmax: 232 bytes in 2 blocks
|
||||
# dhat: At t-end: 0 bytes in 0 blocks
|
||||
# dhat: The data has been saved to dhat-heap.json, and is viewable with dhat/dh_view.html
|
||||
# Part 1: 9001 (4.1ms)
|
||||
```
|
||||
|
||||
The command will output some basic stats to the command-line and generate a `dhat-heap.json `report in the repo root directory.
|
||||
|
||||
You can pass the report a tool like [dh-view](https://nnethercote.github.io/dh_view/dh_view.html) to view a detailed breakdown of heap allocations.
