Struct NumericLiteral 

pub struct NumericLiteral<'a> {
    pub radix: Radix,
    pub prefix: Option<&'a str>,
    pub integer: &'a str,
    pub fraction: Option<&'a str>,
    pub exponent: Option<(&'a str, &'a str)>,
    pub suffix: Option<&'a str>,
}

Fields

radix: Radix

Which radix the literal was represented in.

prefix: Option<&'a str>

The radix prefix, if present.

integer: &'a str

The integer part of the number.

fraction: Option<&'a str>

The fraction part of the number.

exponent: Option<(&'a str, &'a str)>

The exponent separator (b’e’ or b’E’) including preceding underscore if present and the exponent part.

suffix: Option<&'a str>

The type suffix, including preceding underscore if present.

Implementations

impl<'a> NumericLiteral<'a>

pub fn from_lit_kind( src: &'a str, lit_kind: &LitKind, ) -> Option<NumericLiteral<'a>>

Attempts to parse a NumericLiteral from the source string of an ast::LitKind.

pub fn new(lit: &'a str, suffix: Option<&'a str>, float: bool) -> Self

Parses a raw numeric literal string into its structured NumericLiteral parts.

pub fn is_decimal(&self) -> bool

Checks if the literal’s radix is Radix::Decimal

fn split_digit_parts( digits: &str, float: bool, ) -> (&str, Option<&str>, Option<(&str, &str)>)

pub fn format(&self) -> String

Returns literal formatted in a sensible way.

fn group_digits( output: &mut String, input: &str, group_size: usize, partial_group_first: bool, zero_pad: bool, )

Trait Implementations

impl<'a> Debug for NumericLiteral<'a>

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
