Detailed Description

template<size_t N>
class roo_collections::SmallString< N >

Fixed-capacity string stored inline (no heap allocation).

Intended for short, bounded identifiers and other small keys/values where a constant memory footprint is preferred over unbounded growth.

Template Parameters

N	Capacity of the internal storage buffer, in bytes.
