Trait synstructure::MacroResult[][src]

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

    fn into_stream(self) -> TokenStream
        Self: Sized
, { ... } }
Expand description

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

Required methods

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

Provided methods

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.
