Attribute Macro component 

#[component]

Marks a struct as a component

Automatically derives:

• Debug - Required by Component trait
• Clone - Useful for component copying
• PartialEq - Useful for testing and comparison

Also adds #[allow(dead_code)] to prevent warnings on unused fields.

Example

#[component]
struct Position {
    x: f32,
    y: f32,
}

// Expands to:
#[derive(Debug, Clone, PartialEq)]
#[allow(dead_code)]
struct Position {
    x: f32,
    y: f32,
}

Requirements

Component types must be:

• Simple structs (no enums or unions)
• All fields must implement Debug, Clone, PartialEq
