wmtk::history::detail::Reader Class Reference

Reads the bytes of a history, [p, end). what and name say what they are in messages, "<what>: <name> is ...": the kind of history, and a file or the bytes given. A read past the end throws "is truncated", a count that could not fit in what is left "is corrupt". More...

Detailed Description

Reads the bytes of a history, [p, end). what and name say what they are in messages, "<what>: <name> is ...": the kind of history, and a file or the bytes given. A read past the end throws "is truncated", a count that could not fit in what is left "is corrupt".

Member Function Documentation

count()

uint64_t wmtk::history::detail::Reader::count ( const uint64_t  min_bytes = 1 )

inline

A count of items of at least min_bytes each, which the rest of the bytes must hold: a damaged count cannot make the reader allocate more than the bytes could fill.
