Description

This abstract interface provides a means for an algorithm to generically obtain a modifiable, contiguous character buffer of prescribed size. As the author of an algorithm simply declare an rvalue reference as a parameter type.

Instances of this type are intended only to be used once and then destroyed.

Example

The declared function accepts any temporary instance of `arg` to be used for writing:

void algorithm( string_token::arg&& dest );

To implement the interface for your type or use-case, derive from the class and implement the prepare function.
