There's a crate, X, I'm working on a PR for and it used by another crate Y, which is used by program P.
So right now, P depends on Y-1.0.1 and that depends on X-2.5.3.
I am making a change to X so it will be X-2.5.4.
I want to test my change to X on Y & P before I submit it. I think to do this, I will have my X PR update the version to X-2.5.4 and I'll have to make a Y PR to change it to Y-1.0.2 (with a new X-2.5.4 dependency), then I can make P depend on Y-1.0.2.
Given that I don't control either X or Y on crates.io, how can get my local instance of Cargo to notice these changes? I want to do something like
cd x cargo build cargo tell-my-machine-about-it cd ../y cargo build # gets the new version of x cargo tell-my-machine-about-it cd ../p cargo build # gets the new version of y (which has the new version of x)
But I don't think that
cargo tell-my-machine-about-it exists... and clearly I don't know what I should be searching for in Introduction - The Cargo Book
I tried to think through if I should be following the instructions here --- Overriding Dependencies - The Cargo Book --- but it seems weird that I'm modifying the Cargo.toml file with paths in my local system... I don't want to include those in the PR, but I am making some changes to it in the PR, so I'll have to maintain un-committed revisions to the file. I think of what I'm doing as "faking results from crates.io" and so it seems like it should be part of the ambient environment.
Thank you for your help!
