serde-typeinfo

"Serialize" type info to a runtime tag based on serde data model.

Examples

  • u8 integer will be "serialized" into Primitive::U8 enum without its value
use serde_typeinfo::{TypeTag, Primitive};

assert_eq!(
    TypeTag::from_value(&32_u8),
    TypeTag::Primitive(Primitive::U8), // only tag, not includes 32
);
  • User defined struct with serde::Serialize trait implementation will be "serialized" into TypeTag::Struct as its name and its fields' names and types, not includes values.
use serde_typeinfo::{TypeTag, Primitive};
use serde::Serialize;

#[derive(Serialize)]
struct A {
    a: u8,
    b: u8,
}

assert_eq!(
    TypeTag::from_value(&A { a: 2, b: 3 }),
    TypeTag::Struct {
        name: "A",
        fields: vec![
            ("a", Primitive::U8.into()),
            ("b", Primitive::U8.into()),
        ]
    }
);
