Parse Rust's attribute arguments by defining a struct.
See #[derive(StructMeta)]
documentation for details.
use structmeta::StructMeta;
use syn::{parse_quote, Attribute, LitInt, LitStr};
#[derive(StructMeta, Debug)]
struct MyAttr {
x: LitInt,
y: LitStr,
}
let attr: Attribute = parse_quote!(#[my_attr(x = 10, y = "abc")]);
let attr: MyAttr = attr.parse_args().unwrap();
println!("x = {}, y = {}", attr.x, attr.y.value());
This code outputs:
x = 10, y = abc
