Derive Macro ToTokenStream 

#[derive(ToTokenStream)]
{
    // Attributes available to this derive:
    #[OutType]
}

Implement ToTokenStream for a struct or enum with components implementating ToTokenStream.

Basic usage

use rustifact::ToTokenStream;

#[derive(ToTokenStream)]
pub struct MyStruct {
    // fields...
}

#[derive(ToTokenStream)]
pub enum MyEnum {
    // variants...
}

Type mapping

In the case that some components change type under ToTokenStream, like for example String which is mapped to &’static str, a separate output type may be specified with the OutType attribute.

use rustifact::ToTokenStream;

pub struct StructWithStr {
    pub s: &'static str,
}

#[derive(ToTokenStream)]
#[OutType(StructWithStr)]
pub struct StructWithStrIn {
    pub s: String,
}
