1//! # The ArceOS Standard Library
2//!
3//! The [ArceOS] Standard Library is a mini-std library, with an interface similar
4//! to rust [std], but calling the functions directly in ArceOS modules, instead
5//! of using libc and system calls.
6//!
7//! ## Cargo Features
8//!
9//! - CPU
10//! - `smp`: Enable SMP (symmetric multiprocessing) support.
11//! - `fp-simd`: Enable floating point and SIMD support.
12//! - Interrupts:
13//! - Interrupt handling is always available.
14//! - Memory
15//! - `alloc`: Enable dynamic memory allocation.
16//! - `paging`: Enable page table manipulation.
17//! - `tls`: Enable thread-local storage.
18//! - Task management
19//! - Multi-threading and timer-driven scheduling are always available.
20//! - Upperlayer stacks
21//! - `fs`: Enable file system support.
22//! - `ext4fs`: Enable the ext4 filesystem.
23//! - `fatfs`: Enable the FAT filesystem.
24//! - `net`: Enable networking support.
25//! - `dns`: Enable DNS lookup support.
26//! - `display`: Enable graphics support.
27//! - Device drivers are selected directly through `ax-driver/*` features by
28//! board configurations.
