Understanding the Purpose of `Schema.decodeEither` in Type-Safe Parsing

Can someone explain me what is the purpose of

Schema.decodeEither

Schema.decodeEither

if it requires the exact type the schema is parsing? I mean, if I am forced to always provide the right types (for example

"EUR" | "USD"

"EUR" | "USD"

instead of just

string

string

) what is it useful for? It will always suceed, so there is no "Left" case, no?
