Enumeration Type Documentation

state_flags

enum dpp::detail::promise::state_flags

State of a promise.

Enumerator
sf_none	Promise is empty.
sf_has_awaitable	Promise has spawned an awaitable.
sf_awaited	Promise is being awaited.
sf_ready	Promise has a result.
sf_done	Promise has completed, no more results are expected.
sf_broken	Promise was broken - future or promise is gone.
