StructMeta

Parse Rust's attribute arguments by defining a struct.

Documentation

See #[derive(StructMeta)] documentation for details.

Example

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
