Derive Macro Lift 

#[derive(Lift)]
{
    // Attributes available to this derive:
    #[lift]
}

Derive error conversion mappings. A single-field tuple struct can project a source struct field with #[lift(Source, field = name)], generating From<Source> independently of rejection metadata.

An enum arm whose innermost case is written Source::Variant { .. } binds nothing and drops the payload: the destination is a unit variant, or a variant holding one unit leaf. It combines with to = Variant but not with with, into, field or when. Naming fields, Source::Variant { a, .. }, builds the destination from them: a variant with exactly those named fields, or one field whose struct type has exactly those fields.
