### Applying a different format to targets

You can specify your own log format for specific targets by using the `format` method
on `tauri_plugin_log::Target`. You may also wish to call `reset_format` on the builder
to remove the default formatter, which is applied to all targets:

```rust
tauri_plugin_log::Builder::new()
.reset_format()
.targets([
tauri_plugin_log::Target::new(
tauri_plugin_log::TargetKind::Stdout
)
.format(move |out, message, record| {
// custom formatter for stdout
}),
tauri_plugin_log::Target::new(
tauri_plugin_log::TargetKind::LogDir { file_name: None }
)
.format(move |out, message, record| {
// custom formatter for log files
}),
])
.build(),
```

#### Log dates

By default the log plugin uses the UTC timezone to format dates
