[][src]Struct syn::LitInt

pub struct LitInt { /* fields omitted */ }

An integer literal: 1 or 1u16.

This type is available if Syn is built with the "derive" or "full" feature.


impl LitInt[src]

pub fn new(repr: &str, span: Span) -> Self[src]

pub fn base10_digits(&self) -> &str[src]

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.

use syn::LitInt;
use syn::parse::{Parse, ParseStream, Result};

struct Port {
    value: u16,

impl Parse for Port {
    fn parse(input: ParseStream) -> Result<Self> {
        let lit: LitInt = input.parse()?;
        let value = lit.base10_parse::<u16>()?;
        Ok(Port { value })

pub fn suffix(&self) -> &str[src]

pub fn span(&self) -> Span[src]

pub fn set_span(&mut self, span: Span)[src]
