Adding jmespath to dependencies causes compile error

[turettn]

I added jmespath to an existing project, and immediately started getting weird compile errors. I tried replicating with a blank project, added the dependency, and got the same result:

$ cargo new mytest
     Created binary (application) `mytest` package
$ echo 'jmespath = "^0.2.0"' >> mytest/Cargo.toml 
$ cd mytest
$ cargo build

Some errors have detailed explanations: E0603, E0624.

error: could not compile `jmespath`

I'm relatively new to Rust, so if I'm doing something wrong please let me know.

I'm seeing the same errors as well locally. My rustc version is:

$ rustc --version
rustc 1.51.0 (2fd73fabe 2021-03-23)

[davisp]

@turettn This appears to be fixed on master.

[turettn]

@davisp Good catch. Based on the lack of release despite #35, and the lack of commits in the past year, I'm tempted to assume this project is mothballed.

[davisp]

@turettn I did notice there's another crate under jmespatch that is this repo with some patches.

[cetra3]

@davisp & @turettn it's not mothballed, just that PR is massive & will take some time to work through. There is a lot of work to be done to modernise this library & would love your help if you are able.

[turettn]

@cetra3 Excellent news - I completely missed the recent updates to that massive PR.

I'm very much a Rust novice, but I'll take a look at the giant PR and see if there's anything I can do where I won't just be in the way.

@turettn I have published 0.3.0 of this lib which should resolve compilation errors. Let me know how you go!
