Rust pact_consumer v0.10.x compilation error: mismatched types

[luca-iachini]

Hello, I am trying to set up pact_consumer for a demo project. By just importing the pact_consumer dependency:

[dev-dependencies]
pact_consumer = "=0.10.8"
reqwest = "0.11.18"
tokio = "1.28.1"

I get the following error:

error: could not compile `pact_matching` due to 5 previous errors

I am getting the same error for all the "0.10.x" versions.

I'm going to be releasing a new version of pact_consumer soon, but you can try lock pact_models to 1.0.13

[Marwes]

Also seeing this on the 0.9 verifier cli (0.10 doesn't work either). Adding RefUnwindSafe in https://github.com/pact-foundation/pact-reference/commit/261ecf472d468c881c7957fc5b06ad26648e09c3#diff-8e428ff90fe42b124abfa1fcbb60ab275565e95ee0e6a523019c06f083ddc4ae was not a semver compatible change as it affects the public API between crates, causing compilation errors when a crate before the change tries to pull in one with the change.

Running cargo install --locked works around the problem for now.

[mefellows]

Is this fixed now that a new release has gone out?

[rholshausen]

Yes, the dependencies should be correct now.

[mefellows]

Thanks. @Marwes please let us know if there are any issues, I'll close it off for now.
