std::filesystem::hash_value

std::size_t hash_value( const path& p ) noexcept;

Parameters

Return value

A hash value such that if for two paths, p1 == p2 then hash_value(p1) == hash_value(p2).

Exceptions

Notes

Equality of two paths is determined by comparing each component separately, so, for example "a//b" equals "a/b" and has the same hash_value.

hash_value originates from the boost.filesystem library where it was used for interoperability with boost.hash (which calls hash_value where available).
