Trait MacroResult 

pub trait MacroResult {
    // Required method
    fn into_result(self) -> Result<TokenStream>;

    // Provided method
    fn into_stream(self) -> TokenStream
       where Self: Sized { ... }
}

Helper trait describing values which may be returned by macro implementation methods used by this crate’s macros.

Required Methods

fn into_result(self) -> Result<TokenStream>

Convert this result into a Result for further processing / validation.

Provided Methods

fn into_stream(self) -> TokenStream

where Self: Sized,

Convert this result into a proc_macro::TokenStream, ready to return from a native proc_macro implementation.

If into_result() would return an Err, this method should instead generate a compile_error! invocation to nicely report the error.

This method is available if synstructure is built with the "proc-macro" feature.
