Uuid 0.8.2 no_std with features = "v5" is broken
bootstrap-prime opened this issue · comments
What happened?
A clear and concise description of what the bug is.
Uuid 0.8.2 feature "v5" depends on sha1 which requires std even if std is not selected and default-features = false.
Steps to reproduce the behavior:
- Create a no_std project
- add dependency
uuid = { version = "0.8.2", default-features = false, features = ["v5"] } - attempt to compile
- Get an error
error[E0463]: can't find crate for `std`
|
= note: the `thumbv7em-none-eabihf` target may not support the standard library
= note: `std` is required by `sha1` because it does not declare `#![no_std]`
= help: consider building the standard library from source with `cargo build -Zbuild-std`
What were you expecting?

The latest main branch does not cause this error.
Hey @bootstrap-prime 👋 It looks like we missed a default-features = false in that version. This is fixed up on main and in the current 1.0.0-alpha.1 release. I'd suggest upgrading to it if possible. We're currently running through a 1.0.0 release now which you'll end up with if you start with 1.0.0-alpha.1.
1.0.0 is now out in the wild and fixes this issue so I'll go ahead and close this one now. Thanks for the report @bootstrap-prime 🙇
