PFN_kasset_importer_import

typedef b8(* PFN_kasset_importer_import) (const struct kasset_importer *self, u64 data_size, const void *data, void *params, struct kasset *out_asset)

Imports an asset according to the provided params and the importer's internal logic. NOTE: Some importers (i.e. .obj for static meshes) can also trigger imports of other assets. Those assets are immediately serialized to disk/package and not returned here though.

Parameters

self	A constant pointer to the importer itself.
data_size	The size of the data being imported.
data	A constant pointer to a block of memory containing the data being imported.
params	A block of memory containing parameters for the import. Optional in general, but required by some importers.
out_asset	A pointer to the asset being imported.

Returns

True on success; otherwise false.

typedef void(* PFN_kasset_on_hot_reload) (const struct vfs_asset_data *asset_data, const struct kasset *asset)

A function pointer typedef to be used to provide the asset system with a callback function when an asset is written to on-disk (i.e. a hot-reload). This process is synchronous.

PFN_kasset_on_result

typedef void(* PFN_kasset_on_result) (asset_request_result result, const struct kasset *asset, void *listener_inst)

A function pointer typedef to be used to provide the asset asset_system with a calback function when asset loading is complete or failed. This process is asynchronus.

Parameters

result	The result of the asset request.
asset	A constant pointer to the asset that is loaded.
listener_inst	A pointer to the listener, usually passed along with the original request.

Enumeration Type Documentation

asset_request_result

enum asset_request_result

Enumerator
ASSET_REQUEST_RESULT_SUCCESS	The asset load was a success, including any GPU operations (if required).
ASSET_REQUEST_RESULT_INVALID_PACKAGE	The specified package name was invalid or not found.
ASSET_REQUEST_RESULT_INVALID_ASSET_TYPE	The specified asset type was invalid or not found.
ASSET_REQUEST_RESULT_INVALID_NAME	The specified asset name was invalid or not found.
ASSET_REQUEST_RESULT_PARSE_FAILED	The asset was found, but failed to load during the parsing stage.
ASSET_REQUEST_RESULT_GPU_UPLOAD_FAILED	The asset was found, but failed to load during the GPU upload stage.
ASSET_REQUEST_RESULT_INTERNAL_FAILURE	An internal system failure has occurred. See logs for details.
ASSET_REQUEST_RESULT_NO_HANDLER	No handler exists for the given asset. See logs for details.
ASSET_REQUEST_RESULT_NO_IMPORTER_FOR_SOURCE_ASSET	No importer exists for the given asset extension. See logs for details.
ASSET_REQUEST_RESULT_VFS_REQUEST_FAILED	There was a failure at the VFS level, probably a request for an asset that doesn't exist.
ASSET_REQUEST_RESULT_AUTO_IMPORT_FAILED	Returned by handlers who attempt (and fail) an auto-import of source asset data when the binary does not exist.
