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 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.
