Trait IoVectoredBuf

pub trait IoVectoredBuf: 'static {
    type Buf: IoBuf;
    type OwnedIter: OwnedIterator<Inner = Self> + IoBuf;

    // Required methods
    fn iter_buf(&self) -> impl Iterator<Item = MaybeOwned<'_, Self::Buf>>;
    fn owned_iter(self) -> Result<Self::OwnedIter, Self>
       where Self: Sized;

    // Provided method
    unsafe fn io_slices(&self) -> Vec<IoSlice> { ... }
}

A trait for vectored buffers.

Required Associated Types

type Buf: IoBuf

The buffer.

type OwnedIter: OwnedIterator<Inner = Self> + IoBuf

The owned iterator that wraps Self.

Required Methods

fn iter_buf(&self) -> impl Iterator<Item = MaybeOwned<'_, Self::Buf>>

An iterator over the buffers that’s either owned or borrowed with MaybeOwned.

fn owned_iter(self) -> Result<Self::OwnedIter, Self>

where Self: Sized,

Wrap self into an owned iterator.

Provided Methods

unsafe fn io_slices(&self) -> Vec<IoSlice>

Collected IoSlices of the buffers.

Safety

The return slice will not live longer than self. It is static to provide convenience from writing self-referenced structure.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
