serde's borrowing can be treacherous

(This is not super surprising when you think about it, but it bit me recently so I figured I'd write it up.)

TL;DR: Be careful when using &'a str or &'a [u8] with serde deserializers; serde has no way to produce an appropriate compile-time error when zero-copy deserialization isn't possible or just isn't supported. Instead, you'll get a runtime error indefinitely later.

Из-за экранирования данных, главным образом. Для обхода этой проблемы можно использовать Cow<'a, str> с #[serde(borrow)]
