Expansion

Support parsing macros from serde:

// field `b` => [Rename(LitStr { token: "serde rename for b" })]
// field `c` => [Skip]
// field `d` => [Rename(LitStr { token: "rust_xlsxwriter rename for d" }), NumFormat(LitStr { token: "$0.00" })]
// field `e` => [Rename(LitStr { token: "xlsxwriter rename for e" }), NumFormat(LitStr { token: "$0.00" })]
// field `f` => [Skip]
#[derive(_impl::ExcelSerialize, serde::Serialize)]
pub struct A {
    #[serde(rename = "serde rename for b")]
    b: (),
    #[serde(skip)]
    c: (),

    #[rust_xlsxwriter(rename = "rust_xlsxwriter rename for d", num_format = "$0.00")]
    d: (),

    #[xlsxwriter(rename = "xlsxwriter rename for e", num_format = "$0.00")]
    e: (),
    #[xlsxwriter(skip)]
    f: (),
}

Good error report:

// error: `not_exist` is not supported by ExcelSerialize derive macro
//   --> src/main.rs:40:18
//    |
// 40 |     #[xlsxwriter(not_exist)]
//    |                  ^^^^^^^^^
#[derive(_impl::ExcelSerialize, serde::Serialize)]
pub struct B {
    #[xlsxwriter(not_exist)]
    f: (),
}
