The build process hangs up when using this crate

[mbs0221]

Hello, everyone! Here comes a problem!

For many days, I would like to introduce the serde-encrypt into our application. Since it is declared that this crate provides support for no-std, I managed to use this crate as following.

serde-encrypt = { version = "0.7.0", default-features = false }

It failed with unknown problem. It hung up at following dependency for several minutes without any progress. It seems to be a dead loop here.

    Building [=======================> ] 295/297: poly1305                                                                                                                                                                                             

Can anyone provide some suggestions or solutions. Any help would be appreciated here.
