[WIP] esyn
De/Serialization Rust In Rust
Example
fn main() {
use esyn::*;
#[derive(Debug, PartialEq, EsynDe, EsynSer)]
struct Test {
_string: String,
_vec_u32: Vec<u32>,
_opt_i64: Option<i64>,
}
let expect = Test {
_string: "hello".to_string(),
_vec_u32: vec![1, 2, 4],
_opt_i64: Some(-9223372036854775807),
};
let config = r#"
fn main() {
let test = Test {
_string: "hello",
_vec_u32: [1, 2, 4],
};
test._opt_i64 = Some(-9223372036854775807);
}
"#;
let test = EsynBuilder::new()
.set_fn("main")
.set_let("test")
.get_once::<Test>(config)
.unwrap();
assert_eq!(test.get_ref(), &expect);
// Serialization
let code = quote! {
fn main() {
let test = #test;
}
}
.into_pretty()
.unwrap();
println!("{code}");
}
