[#1149]: https://github.com/ratatui-org/ratatui/pull/1149
|

|

The `List` widget now clamps the selected index to the bounds of the list when navigating with
|
||||
`first`, `last`, `previous`, and `next`, as well as when setting the index directly with `select`.
|
||||
|
||||
Previously selecting an index past the end of the list would show treat the list as having a
|
||||
selection which was not visible. Now the last item in the list will be selected instead.

|

In this version, we have focused on enhancing usability and functionality with new features like
|

background styles for LineGauge, palette colors, and various other improvements including
|
||||
improved performance. Also, we added brand new examples for tracing and creating hyperlinks!

|
||||
|
||||
`border::FULL` uses a full block symbol, while `border::EMPTY` uses an
|
||||
empty space. This is useful for when you need to allocate space for the
|
||||
border and apply the border style to a block without actually drawing a
|
||||
border. This makes it possible to style the entire title area or a block
|
||||
rather than just the title content.
|
||||
|
||||
```rust
|
||||
use ratatui::{symbols::border, widgets::Block};
|
||||
let block = Block::bordered().title("Title").border_set(border::FULL);
|
||||
let block = Block::bordered().title("Title").border_set(border::EMPTY);

backend of choice without having to add the backend crates as

dependencies.

`termwiz::` with `ratatui::termwiz::`.

Simplify the List example by removing lifetimes not strictly necessary

his PR removes the items from the prelude that don't form a coherent
|
||||
common vocabulary and adds the missing items that do.
|
||||
|
||||
Based on a comment at
|
||||
<https://www.reddit.com/r/rust/comments/1cle18j/comment/l2uuuh7/>
|
||||
```
|
||||
|
||||
BREAKING CHANGE:The following items have been removed from the prelude:
|
||||
|
||||
- `style::Styled` - this trait is useful for widgets that want to
|
||||
support the Stylize trait, but it adds complexity as widgets have two
|
||||
`style` methods and a `set_style` method.
|
||||
- `symbols::Marker` - this item is used by code that needs to draw to
|
||||
the `Canvas` widget, but it's not a common item that would be used by
|
||||
most users of the library.
|
||||
- `terminal::{CompletedFrame, TerminalOptions, Viewport}` - these items
|
||||
are rarely used by code that needs to interact with the terminal, and
|
||||
they're generally only ever used once in any app.
|
||||
|
||||
The following items have been added to the prelude:
|
||||
|
||||
- `layout::{Position, Size}` - these items are used by code that needs
|
||||
to interact with the layout system. These are newer items that were
|
||||
added in the last few releases, which should be used more liberally.

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.

// Run the example with `cargo run --example tracing` and then view the `tracing.log` file to see
