WebOCaml Programming: Correct + Efficient + Beautiful¶ A textbook on functional programming and data structures in OCaml, with an emphasis on semantics and software engineering. This book is the textbook for CS 3110 Data Structures and Functional Programming at Cornell University. A past title of this book was “Functional Programming in OCaml”. Webany_magic_prefix and any_magic_prefix_from_six_bytes read the magic number for one of the known protocols. They differ in how many bytes they read. any_magic_prefix reads the entire Protocol_version_header.t and then checks if there's any magic prefix in there. The number of bytes in the bin_io representation of a Protocol_version_header.t is not fixed …
WebAinsi, si vous écrivez List.length, OCaml sait qu'il doit chercher la fonction length du module List et, si nécessaire, préalablement charger ce module. À l'inverse, si vous écrivez list.length, OCaml sait qu'il doit chercher le champ length d'un enregistrement nommé list, ce qui est une opération beaucoup plus simple.
