SmolStr has an Arc internally for large strings. This allows
cheap copies of large strings, but we lose that ability
when we convert the SmolStr to a &str and then reconstruct a
SmolStr from that slice.
I was hoping for some larger gains here, considering the impact
of this code change, but it only removes ~50k allocations,
while the impact on the runtime is not noticeable at all.
Still, I believe this is the right thing to do.
Before:
```
allocations: 2338981
Time (mean ± σ): 988.3 ms ± 17.9 ms [User: 690.2 ms, System: 206.4 ms]
Range (min … max): 956.4 ms … 1016.3 ms 10 runs
```
After:
```
allocations: 2287723
Time (mean ± σ): 989.8 ms ± 23.2 ms [User: 699.2 ms, System: 197.6 ms]
Range (min … max): 945.3 ms … 1021.4 ms 10 runs
```
This allows us to cheaply copy the langtype::Type values which
contain such a type. The runtime impact is small and barely noticable
but a sampling profiler shows a clear reduction in samples pointing
at langtype.rs, roughly reducing that from ~8.6% inclusive cost
down to 6.6% inclusive cost.
Furthermore, this allows us to share/intern common types.
Before:
```
Benchmark 1: ./target/release/slint-viewer ../slint-perf/app.slint
Time (mean ± σ): 1.089 s ± 0.026 s [User: 0.771 s, System: 0.216 s]
Range (min … max): 1.046 s … 1.130 s 10 runs
allocations: 3152149
```
After:
```
Time (mean ± σ): 1.073 s ± 0.021 s [User: 0.759 s, System: 0.215 s]
Range (min … max): 1.034 s … 1.105 s 10 runs
allocations: 3074261
```
This is the counter-part, which removes focus from the element if it's currently focused. The window - if focused - may still be focused towards the windowing system.
Updated the version from 1.1 to 1.2
Renamed the header to "Slint Royalty-free Desktop, Mobile, and Web Applications License"
Added definition of "Mobile Application" and grant of right
Moved "Limitations" to 3rd section and "License Conditions - Attributions" to 2nd section
Added flexibility to choose between showing "MadeWithSlint" as a dialog/splash screen or on a public webpage
Moved the para on copyright notices to section under "Limitations"
Just ignore the case where focus has more argument that planed as it has
been reported as an error earlier.
Also fix the error message for calling member function with the wrong
number of argument to not include the base in the count.
Fix#4883
Semi-random selection of clippy topics that were
uncontroversial before:-).
Leaves about 84 deduplicated issues in the code base
according to clippy from nightly.
Since commit 6fefe75a1c the handling
of forward-focus bindings happens before the resolve_expressions pass,
which means that we cannot rely on type mismatch
error handling yet.
Fixes#4475
Achieve this by generating a `focus()` function for such components
and call it from the outside.
This replaces the previous focus handling with what should be cleaner:
- Any `forward-focus: some-element;` is basically syntactic sugar for
`public function focus() { some-element.focus(); }`.
- The init code gets simplified to calling focus() on the root, if it's
available.
Since the `focus()` functions are now generated in the imports pass,
they become visible in the style checker. That means the checker
requires consistent focus handling between the styles.
