0.10.4 broken compatibility with Rust 1.48

[davidhewitt]

https://docs.rs/crate/itertools/0.10.4/source/Cargo.toml contains a resolver key, which was not stable on Rust 1.48 and causes build errors.

Cargo.toml.orig does not contain the key, so this was probably caused by releasing with a nightly or beta toolchain which contains the bug rust-lang/cargo#10954

Would you please be willing to re-release as 0.10.5 with an updated Cargo toolchain?

Hi there, thanks for the report.

@jswrenn I'm no expert on what cargo publish internally does, but I tried a --dry-run with cargo 1.63.0, and it seems that this one does not generate the resolver key in Cargo.toml. I pushed d61d12e - maybe you can cargo publish it?

@davidhewitt Does the problem persist in 0.10.5?

Looking at 0.10.5 via the sources view of docs.rs [1] and comparing it to 0.10.4 [2], this looks resolved to me.

[2] https://docs.rs/crate/itertools/0.10.4/source/Cargo.toml

CI using Rust 1.48 also looks good now. [1] I'd say this is resolved.

Yep, thanks very much for fixing!
