Fields

inner: Connection

experimental_mode: bool

cluster_id: Uuid

Implementations

impl Connection

pub fn open(
    path: &Path,
    experimental_mode: Option<bool>
) -> Result<Connection, Error>

fn set_or_get_experimental_mode(
    sqlite: &mut Connection,
    experimental_mode: Option<bool>
) -> Result<bool, Error>

Sets catalog’s experimental_mode setting on initialization or gets that value.

Note that using None for experimental_mode is appropriate when reading the catalog outside the context of starting the server.

Errors

• If server was initialized and experimental_mode.unwrap() does not match the initialized value.

  This means that experimental mode:

  • Can only be enabled on initialization
  • Cannot be disabled once enabled

Panics

• If server has not been initialized and experimental_mode.is_none().

fn set_or_get_cluster_id(sqlite: &mut Connection) -> Result<Uuid, Error>

Sets catalog’s cluster_id setting on initialization or gets that value.

pub fn get_catalog_content_version(&mut self) -> Result<String, Error>

pub fn set_catalog_content_version(
    &mut self,
    new_version: &str
) -> Result<(), Error>

pub fn load_databases(&self) -> Result<Vec<(i64, String)>, Error>

pub fn load_schemas(&self) -> Result<Vec<(i64, Option<String>, String)>, Error>

pub fn load_roles(&self) -> Result<Vec<(i64, String)>, Error>

pub fn allocate_id(&mut self) -> Result<GlobalId, Error>

pub fn transaction(&mut self) -> Result<Transaction<'_>, Error>

pub fn cluster_id(&self) -> Uuid

pub fn experimental_mode(&self) -> bool

Trait Implementations

impl Debug for Connection

fn fmt(&self, f: &mut Formatter<'_>) -> Result
