That can get quiet messy if you have many fields with many (different) default values.
This crate tries to solve this issue by providing the `#[serde_inline_default]` proc macro.
With this macro set at the struct level (_**before `#[derive(Deserialize)]`/`#[derive(Serialize)]`!, otherwise it's not working correctly**_), you can set default values via `#[serde_inline_default(...)]` for your serde fields inline, without creating an extra function.

Internally, `#[serde_inline_default(...)]` gets expanded to a function which returns the set value and the attribute is replaced with `#[serde(default = "<function name>")]`.
So this macro is just some syntax sugar for you, but can get quiet handy if you want to keep your code clean or write declarative macros / `macro_rules!`.
