error: trait objects without an explicit dyn are deprecated

[reneherrero]

Hi,

I'm getting the following error when trying to compile the library with rust 1.43.1:

error: trait objects without an explicit `dyn` are deprecated
   --> src/fmt.rs:6:29
    |
6   | impl<Word, Error> Write for ::serial::Write<Word, Error=Error>
    |                             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: use `dyn`: `dyn (::serial::Write<Word, Error=Error>)`
    |

Only way I can see to make it compile is by removing #![deny(warnings)] from lib.rs, but that doesn't seem right?

I'm also not getting why I can reference the embedded-hal crate from another project (embedded-hal = "0.2.3") without issues, but if I reference the code (embedded-hal = { path="../../embedded-hal/" }) I get the above mentioned error?

Thanks in advance,

Thanks for the report! This should be resolved in 0.2.4 and in the current (unreleased) branch.
