Description

Objects of this type are forward ranges returned when parsing using the range_rule. Iteration is performed by re-parsing the underlying character buffer. Ownership of the buffer is not transferred; the caller is responsible for ensuring that the lifetime of the buffer extends until it is no longer referenced by the range.

Note
 The implementation may use temporary, recycled storage for type-erasure. Objects of type range are intended to be used ephemerally. That is, for short durations such as within a function scope. If it is necessary to store the range for a long period of time or with static storage duration, it is necessary to copy the contents to an object of a different type.
