Attribute Macro serde_default_utils::serde_inline_default

#[serde_inline_default]

The main macro of this crate. Use it to define default values of fields in structs you Serialize or Deserialize. You do not need to create a extra function to provide the default value, as it is the case in serdes’ implementation of default (#[serde(default = "...")]).

Set this macro on a struct where you use Serialize or Deserialize and use #[serde_inline_default(...)] on the field you want to have a inline default value. Replace the ... with the value you want and it will be set as default if serde needs it.

Note that you must set this macro before #[derive(Serialize)] / #[derive(Deserialize)] as it wouldn’t work properly if set after the derive.

Examples

#[serde_inline_default]
#[derive(Deserialize)]
struct Test {
    #[serde_inline_default(42)]
    value: u32
}
