Failure to resolve dependencies on the `13.0-dev` branch

[John Daniel]

Is your issue REALLY a bug?

• My issue is indeed a bug!
• I am not crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise.

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

Using iced (0.13.0-dev) as a dependency makes cargo unable to resolve all the dependencies.

Cargo.toml

[package]
name = "cool_project"
version = "0.1.0"
edition = "2021"

[dependencies]
iced = { version = "0.13.0-dev", git = "https://github.com/iced-rs/iced"}

Running cargo check:

The issue appeared on 5dc668f.

Forcing the dependency to the commit before solves the issue.

[package]
name = "cool_project"
version = "0.1.0"
edition = "2021"

[dependencies]
# The rev here is needed, due to this commit makes cargo unable to resolve dependencies. 
iced = { version = "0.13.0-dev", git = "https://github.com/iced-rs/iced", rev = "555ee3e"}

Output of cargo check

    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.19s

What is the expected behavior?

Not having dependency conflicts.

Version

master

Do you have any log output?

I see that, downloading the repository and running the examples causes no issues. What makes cargo unable to resolve the dependencies when iced is used as a dependency?

Try to run cargo update manually

That solved it!
