Module error_chain::example_generated [−][src]
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 ErrorKinds get a
Msg variant for basic errors. When strings are converted to
ErrorKinds 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 ErrorKinds 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.
