template<typename T>
struct gaia::ecs::detail::ComponentDesc< T >
Compile-time adapter that converts typed component metadata into a plain ComponentDesc.
- Template Parameters
-
| T | Component type or component wrapper being registered. |
◆ alig()
Returns the payload alignment required by the component storage policy.
- Returns
- Component payload alignment in bytes.
◆ func_cmp()
Builds the equality comparison callback for typed payload values.
- Returns
- Equality callback using operator== when available, otherwise byte comparison.
◆ func_copy()
Builds the copy-assignment callback used for typed payload writes.
- Returns
- Copy-assignment callback for the component payload type.
◆ func_copy_ctor()
Builds the copy-constructor callback used when typed payload storage grows or migrates.
- Returns
- Copy-constructor callback for the component payload type.
◆ func_ctor()
Builds the optional constructor callback for typed AoS payloads.
- Returns
- Constructor callback, or nullptr when construction is trivial or SoA-managed.
◆ func_dtor()
Builds the optional destructor callback for typed AoS payloads.
- Returns
- Destructor callback, or nullptr when destruction is trivial or SoA-managed.
◆ func_load()
Builds the serializer load callback for typed payload values.
- Returns
- Load callback for the component payload type.
◆ func_move()
Builds the move-assignment callback used for typed payload writes.
- Returns
- Move-assignment callback for the component payload type.
◆ func_move_ctor()
Builds the move-constructor callback used when typed payload storage grows or migrates.
- Returns
- Move-constructor callback for the component payload type.
◆ func_save()
Builds the serializer save callback for typed payload values.
- Returns

- Component lookup hash derived from reflected type metadata.
◆ make()
Builds the plain descriptor used by component cache registration.
- Parameters
-
| descName | Normalized component symbol name. |

◆ name()
Returns the reflected component symbol name.
- Returns
- Reflected type name for descriptor registration.
◆ size()
Returns the payload size stored in chunks.

◆ soa()
Populates SoA element sizes for SoA payloads.
- Parameters
-
| soaSizes | Scratch/output storage for per-element byte sizes. |
- Returns
- Number of SoA elements, or 0 for AoS payloads.
◆ storage_type()
Returns the compile-time storage mode requested for the component payload.
