folly::resizeWithoutInitialization

Resizes a container without initializing newly added elements.

Synopsis

Declared in <folly/memory/UninitializedMemoryHacks.h>

inline constexpr /* implementation-defined */ resizeWithoutInitialization = {};

Description

Grows a std::basic_string, std::vector, or any container exposing resize_without_initialization() without constructing or zeroing the new elements. Reading an element added by this call before it has been written to is undefined behavior. See the warning at the top of this header.
