Understanding the ABI

This section provides a brief introduction to the ABI and a few related (advanced) features of Rust that deal with conditional compilation options, data layout conventions, and link options.

The ABI is a set of conventions and standards that compilers and linkers adhere to, for function-calling conventions, and for specifying data layouts (type, alignment, offset).

To understand the significance of the ABI, let's draw an analogy with APIs, which are a well-known concept in application programming. When a program wants to access an external component or library at the source-code level, it looks for the definition of the API exposed by that external component. The external component can be a library or an external service accessible over the network. The API specifies the name of the functions that can be called, the parameters (along with their names and data types) that need to be passed to invoke the function, and the type of value returned from...
