A summary of the possible sets of fields.

EnumMatching(usize, usize, &'a Variant, Vec<FieldInfo<'a>>)

Matching variants of the enum: variant index, variant count, ast::Variant,
fields: the field name is only non-None
in the case of a struct
variant.

instead?
Non-matching variants of the enum, but with all state hidden from
the consequent code. The first component holds Ident
s for all of
the Self
arguments; the second component is a slice of all of the
variants for the enum itself, and the third component is a list of
Ident
s bound to the variant index values for each of the actual
input Self
arguments.

A static method where Self
is a struct.

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
