pub struct FormatOptionsBuilder(/* private fields */);

Helper struct to build a FormatOptions struct.

Implementations

impl FormatOptionsBuilder

pub fn new() -> Self

Creates a new builder with the default options.

pub fn number(self, number: NumberFormat) -> Self

Sets the number format. See NumberFormat for more information.

pub fn scientific(self, scientific: Scientific) -> Self

Sets the scientific notation suffix. See Scientific for more information.

pub fn precision(self, precision: Option<usize>) -> Self

Sets the maximum number of digits to show. If None, the number is formatted with full precision. See FormatOptions::precision for more information.

pub fn separators(self, separators: Separator) -> Self

Sets whether to display separators for large numbers. See Separator for more information.

pub fn show_refs(self, show_refs: ShowRefs) -> Self

Sets whether to print addresses of reference types, such as lists. See ShowRefs for more information.

pub fn build(self) -> FormatOptions

Builds the FormatOptions struct.

Trait Implementations

impl Clone for FormatOptionsBuilder

fn clone(&self) -> FormatOptionsBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatOptionsBuilder

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

Formats the value using the given formatter.

impl Default for FormatOptionsBuilder

fn default() -> FormatOptionsBuilder

Returns the “default value” for a type.

impl PartialEq for FormatOptionsBuilder

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