Trait SpanEncoder

source

pub trait SpanEncoder: Encoder {
    // Required methods
    fn encode_span(&mut self, span: Span);
    fn encode_symbol(&mut self, symbol: Symbol);
    fn encode_expn_id(&mut self, expn_id: ExpnId);
    fn encode_syntax_context(&mut self, syntax_context: SyntaxContext);
    fn encode_crate_num(&mut self, crate_num: CrateNum);
    fn encode_def_index(&mut self, def_index: DefIndex);

}

Expand description

This trait is used to allow encoder specific encodings of certain types. It is similar to rustc_type_ir’s TyEncoder.

Required Methods§

source

fn encode_crate_num(&mut self, crate_num: CrateNum)

As a local identifier, a CrateNum is only meaningful within its context, e.g. within a tcx. Therefore, make sure to include the context when encode a CrateNum.
