serde_vars::source

Enum Expansion 

Source 
pub enum Expansion<T, S = T> {
    Expanded(T),
    Original(S),
}
Expand description

Value returned by certain methods of Source.

The type is used to indicate whether an expansion took place, and in case it did not, give back the original value.

Variants§

§

Expanded(T)

The source expanded the value into a new value.

§

Original(S)

The source returned the original value and did not expand it.
