databake

This crate allows data to write itself into Rust code (bake itself in).

Types that implement the Bake trait can be written into Rust expressions, which allows using Rust code itself as a zero-overhead “serialization” strategy.

Example

use databake::*;
use alloc::borrow::Cow;

let data = [Some((18, Cow::Borrowed("hi")))];
assert_eq!(
    data.bake(&Default::default()).to_string(),
    r#"[Some ((18i32 , alloc :: borrow :: Cow :: Borrowed ("hi")))]"#,
);

Derive

Bake can be automatically derived if the derive Cargo feature is enabled.

use databake::*;

#[derive(Bake)]
#[databake(path = my_crate)]
struct MyStruct {
    pub number: u32,
    pub string: &'static str,
    pub slice: &'static [bool],
}

#[derive(Bake)]
#[databake(path = my_crate)]
struct AnotherOne(pub MyStruct, pub char);

Testing

The [test_bake] macro can be used to assert that a particular expression is a Bake fixed point.

test_bake!(
    AnotherOne,
    const,
    crate::AnotherOne(
        crate::MyStruct {
            number: 17u32,
            string: "foo",
            slice: &[true, false],
        },
        'b',
    ),
    my_crate,
);
