pub struct LitInt { /* fields omitted */ }
Expand description
An integer literal: 1
or 1u16
.
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 })
}
}
