`...52// These functions order key from small to big (say "ascending order").53// There are also reserved order functions with name like skiplist.IntDesc.54//55// For key types out of the pre-defined list, one can write a custom compare function.56// type GreaterThanFunc func (lhs, rhs interface{}) bool57// Such compare function returns true if lhs > rhs. Note that, if lhs == rhs, compare58// function (let the name is "foo") must act as following.59// // if lhs == rhs, following expression must be true60// foo(lhs, rhs) == false && foo(rhs, lhs) == false61// There is another func type named LessThanFunc. It works similar to GreaterThanFunc,62// except the order is big to small.63// Here is a sample to write a compare func.64// type Foo struct {65// value int66// }67//68// // it generates a score on a given key.69// // if key1 > key2, then there must be key1.Score() >= key2.Score().70// // it's optional. it's worth implementing if call compare func is quite expensive.71// func (f *Foo) Score() float64 {72// return float64(f.value)73// }74//75// var greater skiplist.GreaterThanFunc = func(lhs, rhs interface{}) {76// return lhs.(Foo).value > rhs.(Foo).value77// }78// list := skiplist.New(greater)79//80// // descending version is a bit different. mind the func type.81// var less skiplist.LessThanFunc = func(lhs, rhs interface{}) {82// return lhs.(Foo).value < rhs.(Foo).value83// })84// list := skiplist.New(less)85//86// Skiplist uses global rand source in math/rand by default.
