在Golang中处理多个错误的最佳做法

Question

I am writing some code that parses a YAML file and validates the data inside. Each parser returns an error if the value found does not meet the requirements. Right now I am creating an array of errors and setting the return of each call to a different index in the array. My current implementation is working, but it seems wrong and I want to see if there is a better way to accomplish this.

Here is an example

func createStruct(yamlMap map[interface{}]interface{}) (myStruct, error) {
    errs := make([]error, 6)
    s := myStruct{}

    s.Name, errs[0] = getString(yamlMap, "name", true)
    s.Tag, errs[1] = getIntValidRange(yamlMap, "tag", 1, 4094, true)
    s.TaggedPorts, errs[2] = getStringPortList(yamlMap, "tagged_ports", true)
    s.UntaggedPorts, errs[3] = getStringPortList(yamlMap, "untagged_ports", true)
    s.IP, errs[4] = getIPString(yamlMap, "ip", true)
    s.Netmask, errs[5] = getIPString(yamlMap, "netmask", true)

    return s, structCreateErrorChecker(errs)
}

The reason I don't handle each error after each function, is because I want to try to parse everything first and then collect all errors and log them. That is what structCreateErrorChecker() does.

Here is the YAML I am trying to parse (it's come up in the comments). When I say dynamic I mean that there can be any number of these controlling_bridge sections and each vlan section can have any number of vlans.

controlling_bridge_1:
    ip:    "1.1.1.1"
    ports: ["1","2"]
    vlans:
        vlan01:
            name:  "vlan1"
            tag:   1001
            ports: ["1"]
            ip:    "2.2.2.2"
        vlan02:
            name:  "vlan02"
            tag:   1002
            ports: ["3", "4"]
            ip:    "3.3.3.1"

controlling_bridge_2:
    ip:    "1.1.1.1"
    ports: ["1","2"]
    vlans:
        vlan01:
            name:  "vlan1"
            tag:   1001
            ports: ["1"]
            ip:    "2.2.2.2"
        vlan02:
            name:  "vlan02"
            tag:   1002
            ports: ["3", "4"]
            ip:    "3.3.3.1"
