在Go数组中查找所有匹配项

I have an array of structs (struct detailed at bottom)

I want to find all the structs that match certain values for, example, leg and site.

So if leg=101 and site=1024A give back all the structs that match these criteria.

What is the Go manner for doing this?

type JanusDepth struct {
    dataset string
    ob      string
    leg     string  
    site    string  
    hole    string
    age     float64
    depth   float64
    long    float64
    lat     float64
}

Dead simple:

leg      := "101"
site     := "1024A"
filtered := []JanusDepth{}

for _, e := range MyArrayOfStructs {
    if(e.leg == leg && e.site == site) {
        filtered = append(filtered, e)
    }
}

// filtered contains your elements

If your data is ordered on one key, then you can use http://golang.org/pkg/sort/#Search to do a binary search, which is better for performance if the amount of data is moderate to large.
