Pass default arguments to cargo run

Question

I have the following binary crate source structure:

prj
 |
 |__config
 |    |___conf.toml
 |
 |___src
 |    |_...
 |
 |__Cargo.toml

So when performing cargo run I expect the following command to run bin /path/to/prj/config/conf.toml .

Is it possible to config cargo run in Cargo.toml so it passes the absolute path to the config/conf.toml without passing it explicitly every time ?

Not exactly , but Cargo can be configured with command aliases in its configuration files . For example, you could place the following into ${PROJECT_ROOT}/.cargo/config.toml :

[alias]
runx = "run /path/to/config/conf.toml"

And then you'd just do cargo runx .
