Rust Nightly Commit Hash Checker

Usually we expect some new features or fixes to be included into the rust nightly build.
If you already know the corresponding git commit hash, you can use this tool to check whether this commit has been included into the latest nightly build.

Example

You should set some environment variables before running this tool, including USER_TOKEN and USER_NAME of your github account.
These environment variables are required for the Github GraphQL API.
You can also set them in the .env file.

 $ cargo run -- bff216c56f472dd751d3da636027d5e2d821e979

Not found! Nightly build doesn't contain this commit: bff216c56f472dd751d3da636027d5e2d821e979

Notes

This program queries the Github GraphQL API for 5 times. Each time it will fetch 100 ancestor commits of the nightly build. So a total of 500 commits will be checked.
You can adjust the trail_count from the default value of 5 to other values.
