Struct NumberFormat

pub struct NumberFormat { /* private fields */ }

Holds the pattern for the number format and some additional data.

Implementations

impl NumberFormat

pub fn new<S: AsRef<str>>(pattern: S) -> Result<Self, NumberFmtError>

New format from pattern.

pub fn news<S: AsRef<str>>( pattern: S, sym: NumberSymbols, ) -> Result<Self, NumberFmtError>

New format from pattern + symbols

pub fn sym(&self) -> &NumberSymbols

Symbols

pub fn fmt_u<Number: LowerExp + Display>(&self, number: Number) -> String

Formats and unwraps any error. The error is written to the result string using {:?}. So this one may be convenient in some situations, but …

pub fn fmt<Number: LowerExp + Display>( &self, number: Number, ) -> Result<String, NumberFmtError>

Formats.

pub fn fmt_to<Number: LowerExp + Display, W: FmtWrite>( &self, number: Number, out: &mut W, ) -> Result<(), NumberFmtError>

Formats to a buffer.

pub fn parse<F: FromStr>(&self, s: &str) -> Result<F, NumberFmtError>

Parse using the exact format. See ParseNumber::parse_sym()(crate::number::ParseNumber::parse_sym()]

Trait Implementations

impl Clone for NumberFormat

fn clone(&self) -> NumberFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumberFormat

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

Formats the value using the given formatter.

impl Default for NumberFormat

fn default() -> NumberFormat

Returns the “default value” for a type.

impl Display for NumberFormat

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

Formats the value using the given formatter.

impl PartialEq for NumberFormat

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