Crate ioslice 

#![no_std]-friendly wrappers over the std::io::IoSlice and std::io::IoSliceMut, which are shared slices and exclusive slices, respectively, and ABI-compatible with system types for I/O vectors.

Internally, the struct will store the following based on crate features:

• std - wrapping std::io::IoSlice directly, with accessors for it as well as conversion functions and From impls.
• libc (and #[cfg(unix)]) - wrapping libc::iovec directly on platforms that support it. A marker is also stored, to safely wrap the raw pointer, and forcing usage of this API to follow the borrow checker rules.
• (none) - wrapping a regular slice, that may not have the same ABI guarantees as the types from std or libc have.

IoSlice will however implement AsRef<[u8]>, Borrow<[u8]>, and Deref<Target = [u8]> regardless of the features used, so long as the slice is marked as initialized.

IoBox

An owned chunk of memory, that is ABI-compatible with libc::iovec or WSABUF, depending on the platform and Cargo features used.

IoSlice

Traits

CastSlice

A trait for casting slices of different types to and from each other, provided that they have the same memory layout.

CastSliceMut

A trait for casting slices of different types to and from each other, mutably, provided that they have the same memory layout.
