You will likely need Rust 1.45 or newer to compile. The 0.9 series only guarantees compilation on the latest Rust versions, though the upcoming 1.0 version has an MSRV of Rust 1.41.

I probably could backport the changes to make Isahc compatible with 1.41 to 0.9.x, but I'm not sure it is worth it at this point since 1.0 is so close to release.

See also #219.

Yeah,I solved in version isahc = "1.0.0-beta.1".

In addition, I would like to ask about when the official release 1.0 will take place. Any roadmap list?

[sagebind]

It is scheduled before the end of the month. See the tracking issue #25 and watch for an announcement on the announcements board. If you have any feedback after using the beta, I'd love to hear about it on the discussions page!

That said, if this is for a production project right now, I'd advise to use 0.9.x and simply upgrade Rust versions.
