Closes #183
This only applies to
#[derive(Schema)]
(and not#[derive(MaxSize)]
) becauseMaxSize
seems likely to disappear soon (#179) and its trait lives in a different crate (postcard::experimental::max_size
vspostcard_schema
). IfMaxSize
ends up remaining as a derive macro and is moved topostcard_schema
, this attribute can work with it as well.The
syn
upgrade makes it possible to useparse_nested_meta()
for parsing attributes using the conventional structure of builtin attributes and is broken out into #185.
