neopack-derive 1.0.0

Derive macros for neopack Pack and Unpack traits.

Structs

Named structs encode as a neopack List of fields in declaration order.

#[derive(Pack, Unpack)]
struct Point { x: f64, y: f64 }

Enums

Each variant encodes as a neopack Variant with the variant name as the tag.

• Unit: payload is unit()
• Single field: payload is the field directly
• Multiple fields: payload is a List of fields

#[derive(Pack, Unpack)]
enum Shape {
    Empty,
    Circle(f64),
    Rect { w: f64, h: f64 },
}

Attributes

#[pack(bytes)] on a Vec<u8> or [u8; N] field encodes as a byte blob instead of a list of u8 tags.
