In `Cargo.toml` I missspelled "version" and it still worked, but after I corrected it I now get compile errors.

Problem

The code is in this github repo: https://github.com/exo-cortex/simple_axum_button_response
In Cargo.toml I missspelled "version" in the line

tower-http = { verion = "0.4", features = ["fs"] }

Everything still worked fine and compiled without errors.
But once I corrected the mistake my project now does not compile anymore. I don't completely understand what's happening here. While compiling cargo displayed that it compiled tower-html v0.5.2 - so it somehow read the package name, but ignored the malformed version-statement.

I fixed my problem with the newer version (that cargo somehow used), but It is problematic IMHO that cargo does not warn the user of a misspelled dependency version statement; I did not correctly state the version and it still installed some version.
I don't think this is intended.

Steps

1. git clone the repo at https://github.com/exo-cortex/simple_axum_button_response
2. run cargo build
3. correct the misspelled word "verion" in Cargo.toml
4. run cargo build again
   this should give you an errror.

Possible Solution(s)

Check toml file integrity when running cargo commands and warn user.

Cargo had a bug where a missing version was treated as version = "*". After a several year transition period for people to stop relying on the bug, we've fixed it in #13775 which will be released in 1.79

Closing as this appears to be resolved. If there is a reason for us to keep this open, let us know.

btw you should have at least gotten the following (I do follow the reproduction steps)

warning: dependency (tower-http) specified without providing a local path, Git repository, version, or workspace dependency to use. This will be considered an error in future versions
warning: unused manifest key: dependencies.tower-http.verion

You're absolutely right! I somehow didn't see it, but it was there. Thank you.
