Semver hazard due to >= in ratatui dependency

[willcrichton]

Hi, I ran into a semver hazard with this library. I depend on ratatui 0.21. I did cargo update and my library broke because ansi-to-tui 3.1 depends on ratatui 0.22. In general, I believe that using >= is considered an anti-pattern as per the Cargo book:

The resolver algorithm may converge on a solution that includes two copies of a dependency when one would suffice. For example:

# Package A
[dependencies]
rand = "0.7"

# Package B
[dependencies]
rand = ">=0.6"  # note: open requirements such as this are discouraged

In this example, Cargo may build two copies of the rand crate, even though a single copy at version 0.7.3 would meet all requirements. This is because the resolver’s algorithm favors building the latest available version of rand for Package B, which is 0.8.5 at the time of this writing, and that is incompatible with Package A’s specification. The resolver’s algorithm does not currently attempt to “deduplicate” in this situation.

The use of open-ended version requirements like >=0.6 is discouraged in Cargo.

I suppose one fix would be to publish a different version of ansi-to-tui for each 0.x release of ratatui. I'm not sure if there's a better solution.

Initially I was using ratatui = 0.* as a dependency but since they introduced a breaking change on 0.21 that no longer worked.
Maybe I should make a deprecated feature that'd replace the Line the with the older Spans and bump the major version.
Do you think that's a better solution ?

[willcrichton]

I see. It's fine to require that ratatui should actually be 0.22 if they introduced a breaking change. I wouldn't use >= 0.21 as the requirement then, and just specify a dependency on 0.22.

From next release onwards I'll match a major version of this crate to a minor version of ratatui until it reaches 1.0 stable

In #60, I changed this library to point at ratatui-core which should have longer term stability compared with the main crate. This is still in testing, so I want to get out a release of ansi-to-tui and other widgte libs so we can ensure that this idea works across a bunch of different use cases.
