Expand description
askama error type
Feature Interaction
If the feature serde_json
is enabled an
additional error variant Json
is added.
Why not failure
/error-chain
?
Error from error-chain
are not Sync
which
can lead to problems e.g. when this is used
by a crate which use failure
. Implementing
Fail
on the other hand prevents the implementation
of std::error::Error
until specialization lands
on stable. While errors impl. Fail
can be
converted to a type impl. std::error::Error
using a adapter the benefits failure
would
bring to this crate are small, which is why
std::error::Error
was used.
