Struct FfiConnection 

pub struct FfiConnection { /* private fields */ }

FFI-compatible ADBC Connection wrapper.

Represents an active connection to an Exasol database. The connection is lazily established on first use (when creating a statement or performing a transaction operation).

Trait Implementations

impl Connection for FfiConnection

type StatementType = FfiStatement

fn new_statement(&mut self) -> AdbcResult<Self::StatementType>

Allocate and initialize a new statement.

fn cancel(&mut self) -> AdbcResult<()>

Cancel the in-progress operation on a connection.

fn get_info( &self, _codes: Option<HashSet<InfoCode>>, ) -> AdbcResult<Box<dyn RecordBatchReader + Send>>

Get metadata about the database/driver.

fn get_objects( &self, depth: ObjectDepth, catalog: Option<&str>, db_schema: Option<&str>, table_name: Option<&str>, table_type: Option<Vec<&str>>, column_name: Option<&str>, ) -> AdbcResult<Box<dyn RecordBatchReader + Send>>

Get a hierarchical view of all catalogs, database schemas, tables, and columns.

fn get_table_schema( &self, _catalog: Option<&str>, db_schema: Option<&str>, table_name: &str, ) -> AdbcResult<Schema>

Get the Arrow schema of a table.

fn get_table_types(&self) -> AdbcResult<Box<dyn RecordBatchReader + Send>>

Get a list of table types in the database.

fn get_statistic_names(&self) -> AdbcResult<Box<dyn RecordBatchReader + Send>>

Get the names of statistics specific to this driver.

fn get_statistics( &self, _catalog: Option<&str>, _db_schema: Option<&str>, _table_name: Option<&str>, _approximate: bool, ) -> AdbcResult<Box<dyn RecordBatchReader + Send>>

Get statistics about the data distribution of table(s).

fn commit(&mut self) -> AdbcResult<()>

Commit any pending transactions. Only used if autocommit is disabled.

fn rollback(&mut self) -> AdbcResult<()>

Roll back any pending transactions. Only used if autocommit is disabled.

fn read_partition( &self, _partition: impl AsRef<[u8]>, ) -> AdbcResult<Box<dyn RecordBatchReader + Send>>

Retrieve a given partition of data.

impl Drop for FfiConnection

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Optionable for FfiConnection

type Option = OptionConnection

fn set_option( &mut self, key: Self::Option, value: OptionValue, ) -> AdbcResult<()>

Set a post-init option.

fn get_option_string(&self, key: Self::Option) -> AdbcResult<String>

Get a string option value by key.

fn get_option_bytes(&self, key: Self::Option) -> AdbcResult<Vec<u8>>

Get a bytes option value by key.

fn get_option_int(&self, key: Self::Option) -> AdbcResult<i64>

Get an integer option value by key.

fn get_option_double(&self, key: Self::Option) -> AdbcResult<f64>

Get a float option value by key.
