Detailed Description

Concrete mutable metadata map backed by an external span storage.

Enforces compile-time lifetime safety via value_ref and requires an explicit stack state struct to generate a read-only metadata_map view.

Constructor & Destructor Documentation

concrete_metadata_map()

constexpr microfmt::concrete_metadata_map::concrete_metadata_map ( span< property_entry >  storage )

inlineexplicitconstexprnoexcept

Constructs a concrete metadata map over an external span buffer.

Parameters

storage

Caller-owned span of property_entry structures for backing memory.

constexpr metadata_map microfmt::concrete_metadata_map::make_view ( span_iteration_state &  state ) const &

inlineconstexprnoexcept

Exclusively creates a type-erased metadata_map view using caller-provided stack state.

Parameters

state

Reference to a stack-allocated span_iteration_state object.

Returns

A lightweight, zero-allocation metadata_map view.

set()

template<typename T >

constexpr bool microfmt::concrete_metadata_map::set ( microfmt::string_view  key, value_ref< T >  ref  )

inlineconstexprnoexcept

Stores or updates a property safely with type erasure.

Template Parameters

T	Inferred type of the referenced property.

Parameters

key	Property key string view.
ref	Lifetime-bound wrapper ensuring the object is not a temporary.

Returns

true if stored successfully, false if the backing span is full.
