Struct syn::LitInt [−][src]
An integer literal: 1
or 1u16
.
Implementations
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,
[src]
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
