Summary:
This diff replaces code of the form:
```
use failure::Fail;
#[derive(Fail, Debug)]
pub enum ErrorKind {
#[fail(display = "something failed {} times", _0)]
Failed(usize),
}
```
with:
```
use thiserror::Error;
#[derive(Error, Debug)]
pub enum ErrorKind {
#[error("something failed {0} times")]
Failed(usize),
}
```
The former emits an implementation of failure 0.1's `Fail` trait while the latter emits an impl of `std::error::Error`. Failure provides a blanket impl of `Fail` for any type that implements `Error`, so these `Error` impls are strictly more general. Each of these error types will continue to have exactly the same `Fail` impl that it did before this change, but now also has the appropriate `std::error::Error` impl which sets us up for dropping our various dependencies on `Fail` throughout the codebase.
