## Project history and usage

counts is a Rust command-line tool for ad hoc profiling by tallying repeated text lines and presenting frequency and weighted-frequency summaries.

### Project history

The public repository was created in 2018. The README positions `counts` as an improved alternative to the Unix `sort | uniq -c` pipeline for profiling data gathered from logging print statements.

The project reached a 1.0.0 release in 2023 and continued with later 1.0.x releases.

### Adoption history

Official installation is through `cargo install counts`, with Homebrew adding a binary-package route for users who prefer system package managers.

### How it is used

The tool is commonly used by inserting temporary logging into a program, piping or saving those logs, and then using `counts` to aggregate hot paths, loop counts, allocation sizes, or other domain-specific measurements.

The README includes a Firefox heap allocator instrumentation example, showing `counts` applied to millions of log lines and weighted byte totals.

### Why package nerds care

For package nerds, `counts` is interesting because it deliberately packages a Unix-pipeline-shaped workflow as a fast single-purpose Rust binary: no daemon, no config, and no profiler integration required.
