alexcrichton opened PR #1480 from linker-get to master:

This commit adds three new methods to Linker in order to inspect it
after values have been inserted:

• Linker::iter - iterates over all defined values
• Linker::get - lookup a value by its ImportType
• Linker::get_by_name - lookup values based on their name

Closes #1454

Could we factor this out into a method on Linker, something like self.linker.get_one_by_name(module, name) or so? I realize it'll require a special error type to be able to report both "no item named {}" and "too many items named {}", but this seems like it'll be a common use case -- I'm even picturing something like the wasmtime CLI but backed by a Linker so that you can provide multiple modules and then do --invoke.

Could you add a brief mention of what the components of the tuple return are? Looking at the code, I'm not surprised it's module, name, extern, but it feels like something worth making explicit in the docs.

Could we factor out this logic too, with something like self.linker.alias(name, as_name) or so?
