osom_lib

This project implements various data structures and algorithms for use in osom projects and not only.

It also defines stable ABI, in the sense that all types used here are repr(C). Most of the libraries are #![no_std], although some do use os syscalls. Other libraries can optionally enable std support by setting the feature with the same name.

Libraries here try to have as little runtime dependencies as possible. Typically this means only libc and windows-sys dependencies whenever access to the operating system is needed.

osom_lib crates

The libraries here are independent on the operating system and can be used anywhere Rust runs.

• osom_lib This library simply gathers and re-exports other osom libs defined here. It also supports std feature for enabling standard (often meaning: os dependent) implementations.
• osom_lib_reprc defines macros, and traits that help working with #[repr(C)] representations.
• osom_lib_entropy holds tools for generating randomness from the surrounding entropy, i.e. the operating system.
• osom_lib_entropy_cprng implements an entropy generator that generates data from cryptographically secure PRNG, but is seeded from the OS-specific entropy.
• osom_lib_prng defines pseudo random number generator algorithms, including cryptographically secure.
• osom_lib_hash_tables defines several ABI stable hash tables.
• osom_lib_hashes defines several ABI stable hashing functions.
• osom_lib_macros several general macros useful in various context.
• osom_lib_primitives holds several primitives (like Length and CResult) used by other osom libs.
• osom_lib_alloc defines Allocator trait and related stuff.
• osom_lib_arrays defines and implements various ABI stable arrays.
• osom_lib_numbers various helpers and numeric algorithms.
• osom_lib_strings various helpers and algorithms for dealing with strings.
