Struct NumberFormat 

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

Reusable locale-configurable formatting, with explicit separators, affixes, digit alphabet and primary/secondary groups. No implicit OS locale or CLDR dependency is installed. Currency/percent conversion and rounding belong to the caller; this formatter preserves the provided fixed-point value exactly.

Implementations

impl NumberFormat

pub fn prefix(self, prefix: impl Into<Arc<str>>) -> Self

Sets a fixed prefix, such as a currency symbol.

pub fn suffix(self, suffix: impl Into<Arc<str>>) -> Self

Sets a fixed suffix, such as a unit or percentage symbol.

pub fn decimal(self, separator: impl Into<Arc<str>>) -> Self

Sets a nonempty decimal separator. Panics for an empty string.

pub fn grouping( self, separator: impl Into<Arc<str>>, primary: usize, secondary: usize, ) -> Self

Sets integer grouping: (3,3) is 1,234,567; (3,2) is 12,34,567. Panics unless group sizes are between one and eighteen. An empty separator disables grouping.

pub fn digits(self, digits: [char; 10]) -> Self

Supplies ten distinct Unicode digit characters. Panics for duplicates or characters that are not numeric. Formatting records UTF-8 byte identities.

pub fn format( &self, value: FixedNumber, min_integer_digits: usize, ) -> FormattedNumber

Formats an exact value with semantic digit slots independent of separators, affix length and integer growth. At most 256 leading integer digits are permitted. Preparation allocates; keep the result when manually animating formatted text.
