Example

module_ = Wasmer::Module.new(
  Wasmer::Store.new,
  (<<~WAST)
  (module
    (func (export "func") (param i32 i64))
    (global (export "glob") i32 (i32.const 7))
    (table (export "tab") 0 funcref)
    (memory (export "mem") 1))
  WAST
)
instance = Wasmer::Instance.new module_, nil
exports = instance.exports

assert { exports.respond_to? :func }
assert { exports.respond_to? :glob }
assert { exports.respond_to? :tab }
assert { exports.respond_to? :mem }
assert { not(exports.respond_to? :foo) }

assert { exports.func.is_a?(Wasmer::Function) }
assert { exports.mem.is_a?(Wasmer::Memory) }
assert { exports.glob.is_a?(Wasmer::Global) }
assert { exports.tab.is_a?(Wasmer::Table) }
