Struct ioslice::IoSlice

#[repr(transparent)]pub struct IoSlice<'a> { /* fields omitted */ }

A #![no_std]-friendly wrapper over the std::io::IoSliceMut.

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 (with #[cfg(unix)] - wrapping libc::iovec directly on platforms that support it, together with a marker making rustc think this stores a &'a mut [u8].
• (none) - wrapping a regular slice, that may not have the same ABI guarantees as the types from std or libc have.
