Problem with the download crate v0.6.0

[hanusek]

Hello @slowli I have a problem with the download and build the crate.

My compiler: rust 1.54 (required by yocto).

Cargo.toml

[package]
name = "jwt_tests"
version = "0.1.0"
edition = "2018"

[dependencies]
jwt-compact = "0.6.0"

Log:

Hi! The version 0.6.0 is not available in your case because it requires Rust 1.60+ / Rust 2021 edition as specified in the crate manifest. (The cargo message is not very helpful here, unfortunately, but I'm 99.9% sure that this is the cause.)

0.6.0 is also the first version that fixes the bug with no_std support that you've encountered with version 0.5.0. This bug was reported previously (#92); see https://github.com/slowli/jwt-compact/issues/92#issuecomment-1032420283 on a moderately hacky fix. Essentially, the fix boils down to specifying serde_cbor as a direct dependency of your crate.
