Detailed Description

template<typename T, bool Owning = false>
class esphome::ConstVector< T, Owning >

Lightweight read-only view over a const array stored in RODATA (will typically be in flash memory).

Iterators are raw pointers like FixedVector. With Owning = true it can also hold a heap copy it owns (see the specialization below); the default view never frees and has no extra cost.
