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//! These features are exactly the same as those in [axfeat], they are used to
8//! provide users with the selection of features in axfeat, without import
9//! [axfeat] additionally:
10//!
11//! ## Cargo Features
12//!
13//! - CPU
14//!     - `smp`: Enable SMP (symmetric multiprocessing) support.
15//!     - `fp-simd`: Enable floating point and SIMD support.
16//! - Interrupts:
17//!     - `irq`: Enable interrupt handling support.
18//! - Memory
19//!     - `alloc`: Enable dynamic memory allocation.
20//!     - `alloc-tlsf`: Use the TLSF allocator.
21//!     - `alloc-slab`: Use the slab allocator.
22//!     - `alloc-buddy`: Use the buddy system allocator.
23//!     - `paging`: Enable page table manipulation.
24//!     - `tls`: Enable thread-local storage.
25//! - Task management
26//!     - `multitask`: Enable multi-threading support.
27//!     - `sched-fifo`: Use the FIFO cooperative scheduler.
28//!     - `sched-rr`: Use the Round-robin preemptive scheduler.
29//!     - `sched-cfs`: Use the Completely Fair Scheduler (CFS) preemptive scheduler.
30//! - Upperlayer stacks
31//!     - `fs`: Enable file system support.
32//!     - `myfs`: Allow users to define their custom filesystems to override the default.
33//!     - `net`: Enable networking support.
34//!     - `dns`: Enable DNS lookup support.
35//!     - `display`: Enable graphics support.
36//! - Device drivers
37//!     - `bus-mmio`: Use device tree to probe all MMIO devices.
38//!     - `bus-pci`: Use PCI bus to probe all PCI devices.
39//!     - `driver-ramdisk`: Use the RAM disk to emulate the block device.
40//!     - `driver-ixgbe`: Enable the Intel 82599 10Gbit NIC driver.
41//!     - `driver-bcm2835-sdhci`: Enable the BCM2835 SDHCI driver (Raspberry Pi SD card).
