Available on crate feature polars-io only.

Options to serialize logical types to CSV.

The default is to format times and dates as chrono crate formats them.

Fields

time_format: Option<String>

Used for DataType::Time.

datetime_format: Option<String>

Used for DataType::Datetime.

float_precision: Option<usize>

Used for DataType::Float64 and DataType::Float32.

separator: u8

Used as separator.

quote_char: u8

Quoting character.

null: String

Null value representation.

line_terminator: String

String appended after every row.

quote_style: QuoteStyle

When to insert quotes.

Trait Implementations

impl Clone for SerializeOptions

fn clone(&self) -> SerializeOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SerializeOptions

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

Formats the value using the given formatter.

impl Default for SerializeOptions

fn default() -> SerializeOptions

Returns the “default value” for a type.

impl Hash for SerializeOptions

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SerializeOptions

fn eq(&self, other: &SerializeOptions) -> 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.
