Implementations

impl CsvOptions

pub fn with_compression( self, compression_type_variant: CompressionTypeVariant ) -> CsvOptions

Set a limit in terms of records to scan to infer the schema

• default to DEFAULT_SCHEMA_INFER_MAX_RECORD

pub fn with_schema_infer_max_rec(self, max_rec: usize) -> CsvOptions

Set a limit in terms of records to scan to infer the schema

• default to DEFAULT_SCHEMA_INFER_MAX_RECORD

pub fn with_has_header(self, has_header: bool) -> CsvOptions

Set true to indicate that the first line is a header.

• default to true

pub fn has_header(&self) -> bool

True if the first line is a header.

pub fn with_delimiter(self, delimiter: u8) -> CsvOptions

The character separating values within a row.

• default to ‘,’

pub fn with_quote(self, quote: u8) -> CsvOptions

The quote character in a row.

• default to ‘“’

pub fn with_escape(self, escape: Option<u8>) -> CsvOptions

The escape character in a row.

• default is None

pub fn with_file_compression_type( self, compression: CompressionTypeVariant ) -> CsvOptions

Set a CompressionTypeVariant of CSV

• defaults to CompressionTypeVariant::UNCOMPRESSED

pub fn delimiter(&self) -> u8

The delimiter character.

pub fn quote(&self) -> u8

The quote character.

pub fn escape(&self) -> Option<u8>

The escape character.

Trait Implementations

impl Clone for CsvOptions

fn clone(&self) -> CsvOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ConfigField for CsvOptions

fn set(&mut self, key: &str, value: &str) -> Result<(), DataFusionError>

fn visit<V>(&self, v: &mut V, key_prefix: &str, _description: &'static str)

where V: Visit,

impl Debug for CsvOptions

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

Formats the value using the given formatter.

impl Default for CsvOptions

fn default() -> CsvOptions

Returns the “default value” for a type.

impl PartialEq for CsvOptions

fn eq(&self, other: &CsvOptions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&CsvOptions> for CsvWriterOptions

type Error = DataFusionError

The type returned in the event of a conversion error.

fn try_from(value: &CsvOptions) -> Result<CsvWriterOptions, DataFusionError>

Performs the conversion.
