Detailed Description

template<typename T, std::size_t N>
class tinyrobotics::VectorFromArray< T, N >

A simple, fixed-capacity vector backed by std::array for embedded and performance-critical use.

VectorFromArray provides a subset of the std::vector API, but with no dynamic memory allocation. All storage is allocated at compile time, making it suitable for microcontrollers, real-time systems, or any environment where heap usage is undesirable or unavailable.

Features:

push_back() to add elements up to the fixed capacity N
operator[] for element access (no bounds checking)
size() and capacity() for querying current and maximum size
clear() to reset the vector to empty
begin()/end() iterators for range-based for loops

Limitations:

Capacity is fixed at compile time (template parameter N)
Exceeding capacity throws std::out_of_range (can be changed for embedded use)
No erase, insert, or dynamic resizing

Example usage:

VectorFromArray<int, 8> v;
v.push_back(1);
v.push_back(2);
for (auto x : v) {
  Serial.println(x);
}
v.clear();

Template Parameters

T	Element type
N	Maximum number of elements (capacity)
