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.
We can do this because we know that `x < y` cannot create a
`TextCodec<T>` for any `T`. This is because `<` is guaranteed to return
a boolean value, and we simply don't implement `TextCodec<T>` on bool.
This allows stateful or configurable codecs without having to express
all configuration in the type name itself. For example, we could have a
Base64 type with configurable Base64 engines without having to duplicate
the Base64 type itself.
(Note that the different engines in the Base64 crate are values, not
types.)
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.
The API changed here, URI became Uri to be more in line with the coding
style.
Also we don’t attempt to trim them any more because that was only used
in the examples, and nowhere in the text of the specification did it say
that those had to be trimmed.
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.
Paths are already patched in the workspace's [patch.crates-io] block.
Not sure why this was added in the first place.

This depends on XEP-0313 for its MAM metadata, and many others such as
XEP-0198, XEP-0280 and XEP-0352 for the inline features, but we
currently provide those as minidom Elements instead.
Text codecs allow to customize the conversion of data from/to XML,
in particular in two scenarios:
1. When the type for which the behaviour is to be defined comes from a
foreign crate, preventing the implementation of
FromXmlText/IntoXmlText.
2. When there is not one obvious, or more than one sensible, way to
convert a value to XML text and back.
This specification defines a token-based method to streamline
authentication in XMPP, allowing fully authenticated stream
establishment within a single round-trip.
This is more in line with how we handle closely coupled specifications
already. While there are subdirectories for "large" specifications (such
as MUC and PubSub), those only refer to a single XEP document. When
there are multiple separate XEP documents, we have separate modules for
that.
There is at least one branch of the FromStr implementation which passes
user input right into the error struct, so we cannot assume that `'` is
not part of that value.
The previous code didn't build with 1.78:

This seems like a silly reason to pull up the compiler version
requirements, so I fixed it with a trivial modification.
This is bare-bones and is missing many features which we intend to add
in future commits, such as parsing from attributes whose names differ
from the field names and parsing into non-String types.
