Struct FormatOptions 

pub struct FormatOptions<'a> {
    safe: bool,
    null: &'a str,
    date_format: Option<&'a str>,
    datetime_format: Option<&'a str>,
    timestamp_format: Option<&'a str>,
    timestamp_tz_format: Option<&'a str>,
    time_format: Option<&'a str>,
    duration_format: DurationFormat,
    types_info: bool,
    formatter_factory: Option<&'a dyn ArrayFormatterFactory>,
}

Options for formatting arrays

By default nulls are formatted as "" and temporal types formatted according to RFC3339

Equality

Most fields in FormatOptions are compared by value, except formatter_factory. As the trait does not require an Eq and Hash implementation, this struct only compares the pointer of the factories.

Implementations

impl<'a> FormatOptions<'a>

pub const fn new() -> FormatOptions<'a>

Creates a new set of format options

pub const fn with_display_error(self, safe: bool) -> FormatOptions<'a>

If set to true any formatting errors will be written to the output instead of being converted into a std::fmt::Error

pub const fn with_null(self, null: &'a str) -> FormatOptions<'a>

Overrides the string used to represent a null

Defaults to ""

pub const fn with_date_format( self, date_format: Option<&'a str>, ) -> FormatOptions<'a>

Overrides the format used for DataType::Date32 columns

pub const fn with_datetime_format( self, datetime_format: Option<&'a str>, ) -> FormatOptions<'a>

Overrides the format used for DataType::Date64 columns

pub const fn with_timestamp_format( self, timestamp_format: Option<&'a str>, ) -> FormatOptions<'a>

Overrides the format used for DataType::Timestamp columns without a timezone

pub const fn with_timestamp_tz_format( self, timestamp_tz_format: Option<&'a str>, ) -> FormatOptions<'a>

Overrides the format used for DataType::Timestamp columns with a timezone

pub const fn with_time_format( self, time_format: Option<&'a str>, ) -> FormatOptions<'a>

Overrides the format used for DataType::Time32 and DataType::Time64 columns

pub const fn with_duration_format( self, duration_format: DurationFormat, ) -> FormatOptions<'a>

Overrides the format used for duration columns

Defaults to DurationFormat::ISO8601

pub const fn with_types_info(self, types_info: bool) -> FormatOptions<'a>

Overrides if types should be shown

Defaults to false

pub const fn with_formatter_factory( self, formatter_factory: Option<&'a dyn ArrayFormatterFactory>, ) -> FormatOptions<'a>

Overrides the ArrayFormatterFactory used to instantiate custom ArrayFormatters.

Using None causes pretty-printers to use the default ArrayFormatters.

pub const fn safe(&self) -> bool

Returns whether formatting errors should be written to the output instead of being converted into a std::fmt::Error.

pub const fn null(&self) -> &'a str

Returns the string used for displaying nulls.

pub const fn date_format(&self) -> Option<&'a str>

Returns the format used for DataType::Date32 columns.

pub const fn datetime_format(&self) -> Option<&'a str>

Returns the format used for DataType::Date64 columns.

pub const fn timestamp_format(&self) -> Option<&'a str>

Returns the format used for DataType::Timestamp columns without a timezone.

pub const fn timestamp_tz_format(&self) -> Option<&'a str>

Returns the format used for DataType::Timestamp columns with a timezone.

pub const fn time_format(&self) -> Option<&'a str>

Returns the format used for DataType::Time32 and DataType::Time64 columns.

pub const fn duration_format(&self) -> DurationFormat

Returns the DurationFormat used for duration columns.

pub const fn types_info(&self) -> bool

Returns true if type info should be included in a visual representation of batches.

pub const fn formatter_factory(&self) -> Option<&'a dyn ArrayFormatterFactory>

Returns the ArrayFormatterFactory used to instantiate custom ArrayFormatters.

Trait Implementations

impl<'a> Clone for FormatOptions<'a>

fn clone(&self) -> FormatOptions<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for FormatOptions<'a>

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

Formats the value using the given formatter.

impl Default for FormatOptions<'_>

fn default() -> FormatOptions<'_>

Returns the “default value” for a type.

impl Hash for FormatOptions<'_>

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 FormatOptions<'_>

fn eq(&self, other: &FormatOptions<'_>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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