Import rust package with alias in toml - rust

Question

I'm trying to make a simple program checking execution times on two different branches of the same rust project.
I wanted to have my .toml look something like this
[dependencies]
cron_original = { git = "https://github.com/zslayton/cron" }
cron_fork = { git = "https://github.com/koenichiwa/cron", branch = "feature/reimplement-queries"}
And my program look something like this:
fn main() {
let expression = String::from("0-59 * 0-23 ?/2 1,2-4 ? *");
let schedule_orig = cron_original::Schedule::from_str(expression);
let schedule_fork = cron_fork::Schedule::from_str(expression);
// Check difference in execution times on these structs
}
but I'm getting no matching package named 'cron_fork' found. Is there anyway to import a package with a specific alias? I was thinking about creating something that would automate checks like this.

You need to specify package keys for those dependencies so cargo knows that you really want those packages even though you specify a different name:
[dependencies]
cron_original = { git = "https://github.com/zslayton/cron", package="cron" }
cron_fork = { git = "https://github.com/koenichiwa/cron", branch = "feature/reimplement-queries", package="cron" }
See the Renaming dependencies in Cargo.toml section in Specifying Dependencies documentation for details.
