Detailed Description

template<typename T>
class esphome::ConstVector< T >

Lightweight read-only view over a const array stored in RODATA (will typically be in flash memory) Avoids copying data from flash to RAM by keeping a pointer to the flash data.

Similar to std::span but with minimal overhead for embedded systems.
