Trait ReadExtent 

pub trait ReadExtent<'a, N> {
    type Src;
    type SrcIter: Iterator<Item = (ExtentN<N>, Self::Src)>;

    // Required method
    fn read_extent(&'a self, extent: &ExtentN<N>) -> Self::SrcIter;
}

A trait to facilitate the generic implementation of copy_extent.

Some lattice maps, like ChunkMap, have nonlinear layouts. This means that, in order for a writer to receive data efficiently, it must come as an iterator over multiple extents.

Required Associated Types

type Src

type SrcIter: Iterator<Item = (ExtentN<N>, Self::Src)>

Required Methods

fn read_extent(&'a self, extent: &ExtentN<N>) -> Self::SrcIter

SrcIter must return extents that are subsets of extent.
