macro_rules! format_err_spanned {
    ($tokens:expr, $($msg:tt)*) => { ... };
}
Expand description

Creates a syn::Error with the format message and infers the Span using ToTokens.

Parameters

  • The first argument must implement quote::ToTokens in order to infer a Span.
  • The second argument is a format string.
  • The rest are format string arguments.

Note

On stable Rust this might yield higher quality error span information to the user than format_err.
