error: failed to select a version for `ring`.
    ... required by package `rustls v0.14.0`
    ... which is depended on by `hyper-sync-rustls v0.3.0-rc.4`
    ... which is depended on by `rocket_http v0.4.5`
    ... which is depended on by `rocket v0.4.5`
    ... which is depended on by `my-iot v0.84.0 (/Users/eigenein/GitHub/my-iot-rs)`
versions that meet the requirements `^0.13.2` are: 0.13.5

the package `ring` links to the native library `ring-asm`, but it conflicts with a previous package which links to `ring-asm` as well:
package `ring v0.16.15`
    ... which is depended on by `rustls v0.17.0`
    ... which is depended on by `hyper-rustls v0.20.0`
    ... which is depended on by `reqwest v0.10.6`
    ... which is depended on by `my-iot v0.84.0 (/Users/eigenein/GitHub/my-iot-rs)`

failed to select a version for `ring` which could resolve this conflict
