The trait bounds aren't needed on the struct definition, only the impl
block. I think it'd be useful to show the difference here in order to
show students how trait bounds for collection types are usually on the
impl blocks rather than the type itself.
While it's generally better in Rust code to use `String` as the key type
for a `HashMap` than `&str`, for the purposes of our examples having the
extra `to_string` calls makes the example more verbose and confusing for
students. The simple example will work as-is without the `to_string`
calls, so I think it's better to just remove them.
I find that `if let` makes the most sense to use when you don't have an
`else` case, otherwise it's generally clearer to express the same thing
with a `match`. This changes the `if let` example to be (arguably) a bit
more idiomatic and less verbose.
As discovered during #1961, fixed byte offsets tend to break
translations because the translated strings can end up having a
character on the boundary where we slice.

This PR moves the slides for slices and strings into the day 1 section
on references. This seems like the more natural place to introduce
slices since slices are a type of reference. It then also made sense to
me to follow that with the introduction of `&str` and `String`, since
students now have the context to understand what a "string slice" is. I
also removed the strings slide from the types and values section since
it didn't make sense to cover the same topic twice in the same day. I
tested this new organization in my class on Wednesday and it didn't
cause day 1 to take too long.
I was a bit dissatisfied with the test code for the generic min
exercise. We were supposed to be testing that the student wrote the
generic function correctly, but we only test their `min` function with
one type. I rewrote the exercise to test against multiple types, which
required that we use the regular `Ord` trait rather than a custom one. I
tend to prefer using the real items from `std` when we can because it's
a good way to get students familiar with the standard library. I also
removed the custom `Citation` type since it wasn't really important to
the exercise.
The logger exercise comes before the section on generics, and the
purpose of the exercise is for students to get practice writing a trait
implementation, so using generics in the solution is a source of
confusion for students. I've removed the generic and made
`VerbosityFilter` directly hold a `StderrLogger`.

A minor nitpick, but as someone new to the language I did spend a bit
more time than I'd like to admit trying to understand the meaning of
`allow` before realizing this is likely a typo. Maybe I still don't
understand, and in that case I'd appreciate a correction!
Clarify that the basics are stable, but dyn support is still missing.
This slide was outdated and didn't explain the current state of stable
correctly.
This diagram is misleading and I often explain that the character data
of string literals resides in the executable's static data, with vtables
working the same.
These follow the flow of what I actually teach, which spends a
significant amount of time on the latter slide. I think it's worthwhile
to have a real flow documented in the teaching notes, both to make sure
nothing gets forgotten and to structure the experience of teaching.
Because `.zip()` is limited to the shorter length, the `.take()` call
here is unnecessary. When explaining this solution I don't want to have
to explain a call to a method that, used as it is, does nothing.
