`skip_serializing_if` not works when an enum variant is a tuple and the enum has `#[serde(tag = "type", content = "value")]`

1

Like this example, the enum has a serde derive `#[serde(tag = "type", content = "value")]`, and `skip_serializing_if` of the second variant not works: version: serde 1.0.197, serde_json 1.0.115 ```rust #[derive(Debug,...

`StackItem.GetHashCode` probably shouldn't throw any `Exception`.

According to the C# Specification, `GetHashCode()` must have some properties, for example: > The [GetHashCode()](https://learn.microsoft.com/en-us/dotnet/api/system.object.gethashcode?view=net-8.0#system-object-gethashcode) method should not throw exceptions. So, `StackItem.GetHasoCode` probably shouldn't throw any Exception. But in current...

According to the previous two issues(#1193, #1194), there are some different implementations with C# stdlib on determining a `char` is white space or not(and `string.Trim` and `char.IsWhiteSpace` is different too)....

`checked` does not handle the `-x` operation.
