Enum syn_solidity::LitNumber

pub enum LitNumber {
    Int(LitInt),
    Float(LitFloat),
}

An integer or fixed-point number literal: 1 or 1.0.

Variants

Int(LitInt)

Float(LitFloat)

Implementations

impl LitNumber

pub fn new_int(repr: &str, span: Span) -> Self

pub fn new_fixed(repr: &str, span: Span) -> Self

pub fn peek(lookahead: &Lookahead1<'_>) -> bool

pub fn base10_digits(&self) -> &str

Returns the base-10 digits of the literal.

pub fn base10_parse<N>(&self) -> Result<N>

where N: FromStr, N::Err: Display,

Parses the literal into a selected number type.

This is equivalent to lit.base10_digits().parse() except that the resulting errors will be correctly spanned to point to the literal token in the macro input.

pub fn suffix(&self) -> &str

pub fn token(&self) -> Literal
