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.
