# Rust-Struct-Reification

A macro to reify structs and their fields for type-safe runtime invocation and reflective access to fields and attributes

## Example:

```rust

use crate::reify;

reify!{

    struct TestStruct {

        #[some_attr=5]

        pub field1: u64,

        #[macro_attr(Value)]

        field2: Vec,

        field3: Box,

    }

}

impl TestStruct {

    pub fn new() -> TestStruct {

        return TestStruct {

            field1: 42,

            field2: vec![String::from("something"), String::from("else")],

            field3: Box::new(64),

        };

    }

}

fn main() {

    println!("{:?}", TestStruct::get_field_attribute_map());

    // Prints: { "field1": "some_attr=5", "field2": "macro_attr(Value)", "field3": "" }

    println!("{:?}", TestStruct::get_field_attribute("field1"));

    // Prints: Ok(Some("some_attr=5"))

    println!("{:?}", TestStruct::get_field_attribute("field3"));

    // Prints: Ok(None)

    println!("{:?}", TestStruct::get_field_attribute("field4"));

    // Prints: Err(TypedAttributeRetrievalError{ message: "..." })

    let test_struct: TestStruct = TestStruct::new();

    println!("{:?}", test_struct::get_field("field1"));

    // Prints: Ok(Any { .. })

    println!("{:?}", test_struct::get_field_typed::>("field2"))

    // Prints: Ok({ "something", "else" })

}

```
