This allows structs to use the default value for each field defined in
the struct’s `std::default::Default` implementation, rather then the
default value for the field’s type.
```
struct StructDefault {
a: i32,
b: String,
}
impl Default for StructDefault {
fn default() -> StructDefault {
StructDefault{
a: 100,
b: "default".to_string(),
}
}
}
```
The code above will now return `100` for field `a` and `”default”` for
`b`, rather then `0` and `””` respectively.
* move to cargo clippy instead of using the clippy plugin
fixes#729
* non-exectable scripts must be run with `sh`
* don't build serde in the clippy travis job
* only run clippy tests if installing clippy succeeds
* why is travis so picky?
* no more serde_codegen
* serde_test_suite_deps has no features
* don't use empty loops, llvm optimizes them to undefined behaviour
* abort the clippy job when clippy lints are triggered
* use caches on travis to speed up builds
* why are we even using `travis-cargo`?
* need to reinstall clippy frequently due to nightly updates
* command line tools are hard
