Struct NeverBuffer 

pub struct NeverBuffer(/* private fields */);

A buffer that is never used.

Note that this is needed because of the [AsMut<[u8]>] bound required. It is not possible work around this with a local trait. That approach requires a blanket impl which the compiler will complain that the core crate can eventually add a impl for the Infallible type. When that happens, we can remove this local type.

Trait Implementations

impl AsMut<[u8]> for NeverBuffer

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl FragmentedBuffer for NeverBuffer

fn len(&self) -> usize

Gets the total length, in bytes, of this FragmentedBuffer.

fn with_bytes<'a, R, F>(&'a self, _f: F) -> R

where F: for<'b> FnOnce(FragmentedBytes<'b, 'a>) -> R,

Invokes a callback on a view into this buffer’s contents as FragmentedBytes.

fn is_empty(&self) -> bool

Returns true if this FragmentedBuffer is empty.

fn to_flattened_vec(&self) -> Vec<u8>

Returns a flattened version of this buffer, copying its contents into a Vec.
