Struct Puller

pub struct Puller<T> { /* private fields */ }

An adapter from which one can pull elements of type T.

This type is very simple, and just consumes owned Vec<u8> allocations. It is not the most efficient thing possible, which would probably instead be something like the bytes crate (../bytes/) which provides an exclusive view of a shared allocation.
