These modules show an example of code generated by the macro. **IT MUST NOT BE
USED OUTSIDE THIS CRATE**.
This is the basic error structure. You can see that `ErrorKind`
has been populated in a variety of ways. All `ErrorKind`s get a
`Msg` variant for basic errors. When strings are converted to
`ErrorKind`s they become `ErrorKind::Msg`. The "links" defined in
the macro are expanded to the `Inner` variant, and the
"foreign links" to the `Io` variant.
Both types come with a variety of `From` conversions as well:
`Error` can be created from `ErrorKind`, `&str` and `String`,
and the `links` and `foreign_links` error types. `ErrorKind`
can be created from the corresponding `ErrorKind`s of the link
types, as well as from `&str` and `String`.
`into()` and `From::from` are used heavily to massage types into
the right shape. Which one to use in any specific case depends on
the influence of type inference, but there are some patterns that
arise frequently. |
