This allows exactly one arbitrary payload in any element, and is handled
after every other element with a more specific matcher has been parsed.
Both the #[xml(element(n = 1))] meta and its shortcut #[xml(element)]
are allowed and treated the exact same way.
The remaining two were core::str::FromStr and
alloc::collections::BTreeMap.
Note that this doesn’t allow us to be no_std yet.
skip-changelog: This isn’t in any way user-visible, except that some
structs are now slightly smaller.
It was broken in multiple ways:
- xso did not honour it: unknown children and attributes would cause a
parse error even with `--features disable-validation` set on parsers.
For this, we introduce a new feature flag on xso, `non-pedantic`,
which defaults unknown children and attributes to discard instead of
fail.
Note that individual XSOs can still choose to be always pedantic or
always lenient by explicitly declaring the intent via the
`on_unknown_child` and `on_unknown_attribute` metas.
- Many tests in `xmpp_parsers` were broken with `--features
disable-validation`. They now all pass while *still* being rn with
`disable-validation` set: In that case, they test that parsing in fact
succeeds.
This avoids the need for an expensive clone. Since we switched to AsXml
instead of IntoXml, we don't necessarily have to clone the data when
building new elements, only when it's absolutely necessary. The clones
then happen implicitly in the ItemToEvent iterator used internally.
This mostly fixes#86, with the caveat that there's no absolutely cheap
test: On success, the entire element will be copied, while on failure,
you learn about it rather quickly.
These more closely mirror how enums work currently with the macros.
Non-exhaustive enums may be useful though and kind of were the natural
thing to implement.
By removing that, the lint won't trigger for identifiers with trailing
underscores (which become then embedded underscores which normally trips
the `non_camel_case_types` lint).
In 1265f4b, we introduced a change which may cause a conflict of type
names when deriving the traits on two different types. While a
workaround existed (use `mod`s to isolate the implementation), that is
ugly.
This commit allows overriding the choice of type names.
Let’s continue reexporting jid and minidom, but not their inner pub
items, users of this crate can go one level deeper if they need that.
Only xso::error::Error is still useful to reexport, as this is part of
the public API of all of our parsers.
