§Traits and Derive Macros - Rust Book Chapter 10

This module demonstrates traits and derive macros from The Rust Book Chapter 10.

§Key Concepts Demonstrated

  1. Derive Macros for Common Traits (Chapter 10.2)

    • #[derive(Debug)] - Automatic debug formatting
    • #[derive(Clone)] - Automatic cloning implementation
    • #[derive(PartialEq, Eq)] - Equality comparisons

  2. Trait Bounds and Requirements (Chapter 10.2)

    • Why certain traits require others (e.g., Eq requires PartialEq)
    • How derive macros generate implementations

  3. Enums with Derive (Chapter 6.1 + 10.2)

    • Deriving traits for enums
    • All variants must support the derived trait

§Learning Notes

What are derive macros?

  • Compiler-generated trait implementations
  • Reduce boilerplate code
  • Only work for types where all fields implement the trait

Common derive traits:

  • Debug - For {:?} formatting and debugging
  • Clone - For .clone() method
  • PartialEq - For == and != operators
  • Eq - For full equality (requires PartialEq)
  • Copy - For implicit copying (only for stack types)

Structs§

Location
Location information for a node.
ReferenceTree
A reference tree representing the search results
TreeNode
A node in the reference tree.

Enums§

NodeType
Type of node in the reference tree.
