Chapter 16: Type Conversions in Rust

Type conversion in programming refers to changing the type associated with a value or variable, enabling it to be interpreted or used as a different data type. Rust offers a wide range of tools for type conversions, ranging from simple casts with as to powerful traits like From, Into, TryFrom, and TryInto. This chapter provides an in-depth look at Rust's type conversion mechanisms and how they can be used with both standard library types and custom data types. It also explores low-level features like reinterpreting bit patterns with transmute, parsing strings into other types with parse, and detecting unnecessary conversions with tools like cargo clippy.
