Toptal’s GitHub Organization Hijacked: 10 Malicious Packages Published
Threat actors hijacked Toptal’s GitHub org, publishing npm packages with malicious payloads that steal tokens and attempt to wipe victim systems.
github.com/wk8/go-ordered-map
Same as regular maps, but also remembers the order in which keys were inserted, akin to Python's collections.OrderedDict
s.
It offers the following features:
break
the iteration, and in time linear to the number of keys iterated over rather than the total length of the ordered mapinterface{}
scontainer/list
go get -u github.com/wk8/go-ordered-map
Or use your favorite golang vendoring tool!
All go versions >= 1.13 are supported. There's no reason for older versions to not also work, but they're not part of the build matrix.
The full documentation is available on godoc.org.
package main
import (
"fmt"
"github.com/wk8/go-ordered-map"
)
func main() {
om := orderedmap.New()
om.Set("foo", "bar")
om.Set("bar", "baz")
om.Set("coucou", "toi")
fmt.Println(om.Get("foo")) // => bar, true
fmt.Println(om.Get("i dont exist")) // => <nil>, false
// iterating pairs from oldest to newest:
for pair := om.Oldest(); pair != nil; pair = pair.Next() {
fmt.Printf("%s => %s\n", pair.Key, pair.Value)
} // prints:
// foo => bar
// bar => baz
// coucou => toi
// iterating over the 2 newest pairs:
i := 0
for pair := om.Newest(); pair != nil; pair = pair.Prev() {
fmt.Printf("%s => %s\n", pair.Key, pair.Value)
i++
if i >= 2 {
break
}
} // prints:
// coucou => toi
// bar => baz
}
All of OrderedMap
's methods accept and return interface{}
s, so you can use any type of keys that regular map
s accept, as well pack/unpack arbitrary values, e.g.:
type myStruct struct {
payload string
}
func main() {
om := orderedmap.New()
om.Set(12, &myStruct{"foo"})
om.Set(1, &myStruct{"bar"})
value, present := om.Get(12)
if !present {
panic("should be there!")
}
fmt.Println(value.(*myStruct).payload) // => foo
for pair := om.Oldest(); pair != nil; pair = pair.Next() {
fmt.Printf("%d => %s\n", pair.Key, pair.Value.(*myStruct).payload)
} // prints:
// 12 => foo
// 1 => bar
}
There are several other ordered map golang implementations out there, but I believe that at the time of writing none of them offer the same functionality as this library; more specifically:
string
keys, its Delete
operations are linearDelete
operations are linearDelete
and Get
operations are linear, iterations trigger a linear memory allocationFAQs
