|
//! libfringe is a library implementing safe, lightweight context switches,
|
|
//! without relying on kernel services. It can be used in hosted environments
|
|
//! (using `std`) as well as on bare metal (using `core`).
|
|
//!
|
|
//! It provides the following safe abstractions:
|
|
//!
|
|
//! * an implementation of generators,
|
|
//! [Generator](generator/struct.Generator.html).
|
|
//!
|
|
//! It also provides the necessary low-level building blocks:
|
|
//!
|
|
//! * a trait that can be implemented by stack allocators,
|
|
//! [Stack](struct.Stack.html);
|
|
//! * a wrapper for using slice references as stacks,
|
|
//! [SliceStack](struct.SliceStack.html);
|
|
//! * a stack allocator based on `Box<[u8]>`,
|
|
//! [OwnedStack](struct.OwnedStack.html);
|
|
//! * a stack allocator based on anonymous memory mappings with guard pages,
|
|
//! [OsStack](struct.OsStack.html).
