template <typename RangeContainer, typename KeyType>struct DefaultRangeTraits
Defined at line 21 of file ../../zircon/system/ulib/range/include/range/range.h
Provides default mechanisms for accessing and updating the range within the
RangeContainer. This abstraction allows customized versions of |Range| to
access these semantics from arbitrary containers.
Public Methods
KeyType Start (const RangeContainer & obj)Returns the start of the range (inclusive).
Defined at line 23 of file ../../zircon/system/ulib/range/include/range/range.h
KeyType End (const RangeContainer & obj)Returns the end of the range (exclusive).
Defined at line 26 of file ../../zircon/system/ulib/range/include/range/range.h
zx_status_t Update (const RangeContainer * other, KeyType start, KeyType end, RangeContainer * obj)Updates |obj| with a new |start| and |end|.
ARGUMENTS:
If |other| is nullptr, then |obj| is being updated independently (typically,
when the range is shrinking).
If |other| is not nullptr, then |obj| is being updated due to a merge with |other|.
|obj| must not be nullptr.
BEHAVIOR:
- If the merge with |other| is valid, |Start()| and |End()| should be updated to return the
new values, and ZX_OK should be returned.
- If the merge with |other| is invalid, an error status should be returned, and |Start()|
and |End()| must return unmodified values.
- If |other| is null, then ZX_OK must be returned.
