f99c224fc1 feat: impl WidgetRef for Fn(Rect, &mut Buffer)
This allows you to treat any function  that takes a `Rect` and a mutable
reference a `Buffer` as a widget in situations where you don't want to
create a new type for a widget.

Example:

```rust
fn hello(area: Rect, buf: &mut Buffer) {
    Line::raw("Hello").render(area, buf);
}

frame.render_widget(&hello, frame.size());
frame.render_widget_ref(hello, frame.size());
```

8061813f32 refactor: expand glob imports (#1152)
Consensus is that explicit imports make it easier to understand the
example code. This commit removes the prelude import from all examples
and replaces it with the necessary imports, and expands other glob
imports (widget::*, Constraint::*, KeyCode::*, etc.) everywhere else.
Prelude glob imports not in examples are not covered by this PR.

See https://github.com/ratatui-org/ratatui/issues/1150 for more details.

74a32afbae feat: re-export backends from the ratatui crate (#1151)
`crossterm`, `termion`, and `termwiz` can now be accessed as
`ratatui::{crossterm, termion, termwiz}` respectively. This makes it
possible to just add the Ratatui crate as a dependency and use the
backend of choice without having to add the backend crates as
dependencies.

To update existing code, replace all instances of `crossterm::` with
`ratatui::crossterm::`, `termion::` with `ratatui::termion::`, and
`termwiz::` with `ratatui::termwiz::`.

f429f688da docs(examples): Remove lifetimes from the List example (#1132)
Simplify the List example by removing lifetimes not strictly necessary
to demonstrate how Ratatui lists work. Instead, the sample strings are
copied into each `TodoItem`. To further simplify, I changed the code to
use a new TodoItem::new function, rather than an implementation of the
`From` trait.

4770e71581 refactor(list)!: remove deprecated start_corner and Corner (#759)
`List::start_corner` was deprecated in v0.25. Use `List::direction` and
`ListDirection` instead.

```diff
- list.start_corner(Corner::TopLeft);
- list.start_corner(Corner::TopRight);
// This is not an error, BottomRight rendered top to bottom previously
- list.start_corner(Corner::BottomRight);
// all becomes
+ list.direction(ListDirection::TopToBottom);
```

```diff
- list.start_corner(Corner::BottomLeft);
// becomes
+ list.direction(ListDirection::BottomToTop);
```

`layout::Corner` is removed entirely.

70df102de0 build(bench): improve benchmark consistency (#1126)
Codegen units are optimized on their own. Per default bench / release
have 16 codegen units. What ends up in a codeget unit is rather random
and can influence a benchmark result as a code change can move stuff
into a different codegen unit → prevent / allow LLVM optimizations
unrelated to the actual change.

9bd89c218a refactor(clippy): enable breaking lint checks (#988)
We need to make sure to not change existing methods without a notice.
But at the same time this also finds public additions with mistakes
before they are even released which is what I would like to have.

This renames a method and deprecated the old name hinting to a new name.
Should this be mentioned somewhere, so it's added to the release notes?
It's not breaking because the old method is still there.

2cfe82a47e refactor(buffer): deprecate assert_buffer_eq! in favor of assert_eq! (#1007)
- Simplify `assert_buffer_eq!` logic.
- Deprecate `assert_buffer_eq!`.
- Introduce `TestBackend::assert_buffer_lines`.

Also simplify many tests involving buffer comparisons.

For the deprecation, just use `assert_eq` instead of `assert_buffer_eq`:

```diff
-assert_buffer_eq!(actual, expected);
+assert_eq!(actual, expected);
```

---

I noticed `assert_buffer_eq!` creating no test coverage reports and
looked into this macro. First I simplified it. Then I noticed a bunch of
`assert_eq!(buffer, …)` and other indirect usages of this macro (like
`TestBackend::assert_buffer`).

The good thing here is that it's mainly used in tests so not many
changes to the library code.

0a164965ea fix: use to_string to serialize Color (#934)
Since deserialize now uses `FromStr` to deserialize color, serializing
`Color` RGB values, as well as index values, would produce an output
that would no longer be able to be deserialized without causing an
error.


Color::Rgb will now be serialized as the hex representation of their
value.
For example, with serde_json, `Color::Rgb(255, 0, 255)` would be
serialized as `"#FF00FF"` rather than `{"Rgb": [255, 0, 255]}`.

Color::Indexed will now be serialized as just the string of the index.
For example, with serde_json, `Color::Indexed(10)` would be serialized
as `"10"` rather than `{"Indexed": 10}`.

Other color variants remain the same.

0207160784 fix(line): line truncation respects alignment (#987)
When rendering a `Line`, the line will be truncated:
- on the right for left aligned lines
- on the left for right aligned lines
- on bot sides for centered lines

E.g. "Hello World" will be rendered as "Hello", "World", "lo wo" for
left, right, centered lines respectively.

### `Rect::inner` takes `Margin` directly instead of reference ([#1008])
[#1008]: https://github.com/ratatui-org/ratatui/pull/1008
`Margin` needs to be passed without reference now.
```diff
-let area = area.inner(&Margin {
+let area = area.inner(Margin {
vertical: 0,
horizontal: 2,
});
```
### `Buffer::filled` takes `Cell` directly instead of reference ([#1148])
[#1148]: https://github.com/ratatui-org/ratatui/pull/1148
`Buffer::filled` moves the `Cell` instead of taking a reference.
```diff
-Buffer::filled(area, &Cell::new("X"));
+Buffer::filled(area, Cell::new("X"));
```
### `Stylize::bg()` now accepts `Into<Color>` ([#1103])
[#1103]: https://github.com/ratatui-org/ratatui/pull/1103
Previously, `Stylize::bg()` accepted `Color` but now accepts `Into<Color>`. This allows more
flexible types from calling scopes, though it can break some type inference in the calling scope.
### Remove deprecated `List::start_corner` and `layout::Corner` ([#757])
[#757]: https://github.com/ratatui-org/ratatui/pull/757
`List::start_corner` was deprecated in v0.25. Use `List::direction` and `ListDirection` instead.
```diff
- list.start_corner(Corner::TopLeft);
- list.start_corner(Corner::TopRight);
// This is not an error, BottomRight rendered top to bottom previously
- list.start_corner(Corner::BottomRight);
// all becomes
+ list.direction(ListDirection::TopToBottom);
```
```diff
- list.start_corner(Corner::BottomLeft);
// becomes
+ list.direction(ListDirection::BottomToTop);

`layout::Corner` was removed entirely.

### Run CI tests before pushing a PR
We're using [cargo-husky](https://github.com/rhysd/cargo-husky) to automatically run git hooks,
which will run `cargo make ci` before each push. To initialize the hook run `cargo test`. If
`cargo-make` is not installed, it will provide instructions to install it for you. This will ensure
that your code is formatted, compiles and passes all tests before you push. If you need to skip this
check, you can use `git push --no-verify`.
Running `cargo make ci` before pushing will perform the same checks that we do in the CI process.
It's not mandatory to do this before pushing, however it may save you time to do so instead of
waiting for GitHub to run the checks.
