Officeyutong opened issue #5788:

I'm trying to call an exported function with signature func (seq: list<s64>) -> s64, but I find that I can't construct wasmtime::component::Val::List(wasmtime::component::values::List()) since wasmtime::component::values::List is not public.

Feature

Add pub to https://github.com/bytecodealliance/wasmtime/blob/e10094dcd6d0354628255a6f2e69c1e4c327d6e7/crates/wasmtime/src/component/mod.rs#L16

Benefit

If accepted, We can invoke functions which contains a param with type list

Implementation

Just add a pub prefix

Alternatives

May be no alternatives available?

At the moment, you can construct a list Val by way of wasmtime::component::types::List::new_val https://docs.rs/wasmtime/latest/wasmtime/component/types/struct.List.html#method.new_val - does that meet your needs?

I think it would be ok to make the values mod public, just on the grounds that if the Val enum is public, the types in all of its variants should be as well (https://docs.rs/wasmtime/latest/wasmtime/component/enum.Val.html), but I don't know if there is something about the design of using the types module to construct Val vs the direct use of the enum that I am missing. @alexcrichton what do you think?

If we choose not to make those types public we should note the preferred way to construct those variants in the docs for Val.

The original intention was to reexport everything necessary form the values module into the top-level component module, so this may be a forgotten reexport?

Ok! I'll add the forgotten reexports :)
