Struct tengwar::characters::numeral::Numeral

pub struct Numeral {
    pub value: isize,
    pub base_10: bool,
    pub ordinal: bool,
    pub lines: bool,
    pub little_endian: bool,
}

A numeric value, paired with formatting information.

Fields

value: isize

Numeric value.

base_10: bool

Whether the number will be displayed in Decimal, base 10, rather than in Duodecimal, base 12.

ordinal: bool

Whether the number is ordinal (“first”), rather than cardinal (“one”).

lines: bool

Whether the base of the number will be denoted with lines, rather than with dots.

little_endian: bool

Whether the less significant digits of will be written first. This is the style preferred by the Eldar, but as the least significant digit is marked, it can go either way without ambiguity.

Implementations

impl Numeral

pub const PREF_NEG_OUT: char = '-'

Prefix to be prepended to the output form of a negative number.

pub const PREF_POS_OUT: char = '+'

Prefix to be prepended to the output form of a positive number.

pub const SUFF_ORD_OUT: char = '\u{e018}'

Suffix to be appended to the output form of an ordinal number.

pub const fn new(value: isize, base_10: bool) -> Self

Define a value in either Base-10 or Base-12.

pub const fn decimal(value: isize) -> Self

Define a Base-10 decimal value.

pub const fn duodecimal(value: isize) -> Self

Define a Base-12 duodecimal, or dozenal, value.

pub const fn with_decimal(self, decimal: bool) -> Self

pub const fn with_lines(self, lines: bool) -> Self

pub const fn with_ordinal(self, ordinal: bool) -> Self

impl Numeral

pub fn parse(slice: &[char]) -> Option<(Self, usize)>

Try to extract a numeric value from a slice of chars. If successful, returns a new Numeral, along with the number of chars that were processed in order to find it.
