Trait Expand 

Source 
pub trait Expand<O> {
    // Required method
    fn expand<'c>(&self, ctx: GeneralContext<'c>, out: &mut O) -> Result<()>;
}
Expand description

Convenience trait providing item.expand()

Implementations of this are often specific to the ExpansionOutput.

Having this as a separate trait, rather than hanging it off ExpansionOutput, makes the expansion method more convenient to call.

It also avoids having to make all of these expansion methods members of the ExpansionOutput trait.

Required Methods§

Source

fn expand<'c>(&self, ctx: GeneralContext<'c>, out: &mut O) -> Result<()>
