Struct ArrowExportOptions 

pub struct ArrowExportOptions {
    pub batch_size: usize,
    pub null_value: Option<String>,
    pub schema: Option<Arc<Schema>>,
    pub column_separator: char,
    pub column_delimiter: char,
    pub host: String,
    pub port: u16,
    pub use_encryption: bool,
}

Options for Arrow export operations.

Fields

batch_size: usize

Number of rows per RecordBatch (default: 1024)

null_value: Option<String>

Custom NULL value representation in CSV (default: empty string)

schema: Option<Arc<Schema>>

Optional explicit Arrow schema (if not provided, will be inferred)

column_separator: char

Column separator in CSV (default: ‘,’)

column_delimiter: char

Column delimiter/quote character (default: ‘“’)

host: String

Exasol host for HTTP transport connection. This is typically the same host as the WebSocket connection.

port: u16

Exasol port for HTTP transport connection. This is typically the same port as the WebSocket connection.

use_encryption: bool

Whether to use TLS for the HTTP transport connection. Default is false because the main WebSocket connection typically already handles TLS encryption.

Implementations

impl ArrowExportOptions

pub fn new() -> Self

Creates new ArrowExportOptions with default values.

pub fn with_batch_size(self, batch_size: usize) -> Self

pub fn with_null_value(self, null_value: impl Into<String>) -> Self

pub fn with_schema(self, schema: Arc<Schema>) -> Self

pub fn with_column_separator(self, sep: char) -> Self

pub fn with_column_delimiter(self, delim: char) -> Self

pub fn exasol_host(self, host: impl Into<String>) -> Self

Sets the Exasol host for HTTP transport connection.

This is typically the same host as the WebSocket connection.

pub fn exasol_port(self, port: u16) -> Self

Sets the Exasol port for HTTP transport connection.

This is typically the same port as the WebSocket connection.

pub fn use_encryption(self, use_encryption: bool) -> Self

Sets whether to use TLS for the HTTP transport connection.

Default is false because the main WebSocket connection typically already handles TLS encryption for the control channel.

impl Clone for ArrowExportOptions

fn clone(&self) -> ArrowExportOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ArrowExportOptions

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