Struct NumberFormat 

pub struct NumberFormat {
    pub style: NumberStyle,
    pub currency: Option<&'static str>,
    pub currency_sign: CurrencySign,
    pub unit: Option<&'static str>,
    pub unit_display: UnitDisplay,
    pub minimum_fraction_digits: Option<u8>,
    pub maximum_fraction_digits: Option<u8>,
    pub use_grouping: bool,
}

The formatOptions subset these components use.

Fields

style: NumberStyle

How the number is styled.

currency: Option<&'static str>

ISO 4217 code, e.g. "USD". Rendered as a symbol when one is known.

currency_sign: CurrencySign

How negative currency amounts are written.

unit: Option<&'static str>

A CLDR unit identifier, e.g. "kilogram".

unit_display: UnitDisplay

How a unit is written.

minimum_fraction_digits: Option<u8>

Minimum number of fraction digits, if set.

maximum_fraction_digits: Option<u8>

Maximum number of fraction digits, if set.

use_grouping: bool

Whether digit groups are separated.

Implementations

impl NumberFormat

pub fn decimal() -> Self

{style: "decimal"}, the default format.

pub fn percent() -> Self

{style: "percent"} — v3’s default for ProgressBar and Meter.

pub fn currency(code: &'static str) -> Self

{style: "currency", currency: code}.

pub fn unit(name: &'static str) -> Self

{style: "unit", unit: name}.

pub fn currency_sign(self, sign: CurrencySign) -> Self

Sets how negative currency amounts are written.

pub fn unit_display(self, display: UnitDisplay) -> Self

Sets how a unit is written.

pub fn minimum_fraction_digits(self, n: u8) -> Self

Sets the minimum number of fraction digits.

pub fn maximum_fraction_digits(self, n: u8) -> Self

Sets the maximum number of fraction digits.

pub fn use_grouping(self, v: bool) -> Self

Sets whether digit groups are separated.

pub fn format(&self, value: f64) -> String

Formats value, applying the style’s own scaling (percent × 100).
