Rust Digger: 47,764 (32.92%) of the crates include a Cargo.lock file

Date: 2024.05.08

Should a crate include a Cargo.lock file?

I think the general idea is that executables should include Cargo.lock but libraries should not, but the goal here is to present the statistics collected by the Rust Digger as to what people actually do.

name	value	percentage
Total	145,087	100%%
Crates with Cargo.lock file	47,764	32.92%
Crates with Cargo.lock file and with src/main.rs file	27,484	18.94%
Crates with Cargo.lock file but without src/main.rs file	20,280	13.97%
Crates without Cargo.lock file	97,323	67.07%
Crates without Cargo.lock but with src/main.rs file	3,115	2.14%
Crates without Cargo.lock and without src/main.rs file	94,208	64.93%

This data is collected after downloading and unzipping the released crates from Crates.io One serious caveat is that a crate does not need to have a main.rs file in order to be executable. One can also map files to be the binary of a crate using the [[bin]] field. The Rust-Digger does just that, but as of today it does not take this information in account.

The above is a snapshot of the data as we have today. The up-to-date data can be found on the Stats pages.
