Trait TTMacroExpander 

pub trait TTMacroExpander: Any {
    // Required method
    fn expand<'cx, 'a: 'cx>(
        &'a self,
        ecx: &'cx mut ExtCtxt<'_>,
        span: Span,
        input: TokenStream,
    ) -> MacroExpanderResult<'cx>;
}

Represents a thing that maps token trees to Macro Results

Required Methods

fn expand<'cx, 'a: 'cx>( &'a self, ecx: &'cx mut ExtCtxt<'_>, span: Span, input: TokenStream, ) -> MacroExpanderResult<'cx>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
