Object containing all opened Tables in read-only mode.

This is an encapsulated object that contains all available Table’s in read-only mode.

It is a Sealed trait and is only implemented on a (tuple, containing, all, table, types, ...).

This is used to return a single object from functions like OpenTables::open_tables rather than the tuple containing the tables itself.

To replace tuple.0 style indexing, field_accessor_functions() are provided on this trait, which essentially map the object to fields containing the particular database table, for example:

let tables = open_tables();

// The accessor function `block_infos()` returns the field
// containing an open database table for `BlockInfos`.
let _ = tables.block_infos();

Required Methods

fn transaction_blobs(&self) -> &impl DatabaseRo<TransactionBlobs>

Access an opened TransactionBlobs database.

fn transaction_infos(&self) -> &impl DatabaseRo<TransactionInfos>

Access an opened TransactionInfos database.

fn cached_verification_state(&self) -> &impl DatabaseRo<CachedVerificationState>

Access an opened CachedVerificationState database.

fn spent_key_images(&self) -> &impl DatabaseRo<SpentKeyImages>

Access an opened SpentKeyImages database.

fn known_blob_hashes(&self) -> &impl DatabaseRo<KnownBlobHashes>

Access an opened KnownBlobHashes database.

fn all_tables_empty(&self) -> Result<bool, RuntimeError>

This returns true if all tables are empty.

Errors

This returns errors on regular database errors.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
