Detailed Description

View to some memory resource without life-time control.

Memory view allows to inspect raw structure of a particular buffer without explicit control over life time of without costly copy operation to move data from one place into another. Use views to access data and then to copy values or fill values from your own data source.

Note: Memory view does not control type and layout of data. Thus, be cautions when modifying data through the view.
