pub struct LitInt { /* private fields */ }
Expand description
An integer literal: 1
or 1u16
.
Implementations
sourceimpl LitInt
impl LitInt
pub fn new(repr: &str, span: Span) -> Self
pub fn base10_digits(&self) -> &str
sourcepub fn base10_parse<N>(&self) -> Result<N> where
N: FromStr,
N::Err: Display,
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::parse::{Parse, ParseStream, Result};

value: u16,
}
impl Parse for Port {

let value = lit.base10_parse::<u16>()?;
Ok(Port { value })
