Implementations

impl InvalidToken

pub fn to_compile_error(&self) -> TokenStream

Returns a token stream representing compile_error!("msg"); where "msg" is the output of self.to_string(). Panics if called outside of a proc-macro context!

pub fn to_compile_error2(&self) -> TokenStream

Like to_compile_error, but returns a token stream from proc_macro2 and does not panic outside of a proc-macro context.
