[−][src]Trait flatdata::Archive
A flatdata archive representing serialized data.
Each archive in generated code implements this trait.
Associated Constants
const NAME: &'static str
Name of the archive.
const SCHEMA: &'static str
Schema of the archive.
Used for verifying the integrity of the archive when opening.
Required methods
fn open(storage: Rc<dyn ResourceStorage>) -> Result<Self, ResourceStorageError>
Opens the archive with name NAME
and schema SCHEMA
in the given
storage for reading.
When opening the archive, the schema of the archive and the schema
stored in the storage are compared as strings. If there is a
difference, an Error [ResourceStorageError::WrongSignature
](enum.
ResourceStorageError.html) is returned containing a detailed diff
of both schemata.
All resources are in the archive are also opened and their schemata are verified. If any non-optional resource is missing or has a wrong signature (unexpected schema), the operation will fail. Therefore, it is not possible to open partially written archive.
