sortby.go

type Chain Uses

type Chain []LessFn

Chain is a list of LessFns, each of which sorts a single aspect of your object. Nil LessFns will be ignored.

func (Chain) Use Uses

func (c Chain) Use(i, j int) bool

Use is a sort-compatible LessFn that actually executes the full chain of comparisons.

type LessFn Uses

type LessFn func(i, j int) bool

LessFn is the type of the function which compares element i with element j of a given slice. Unlike the stdlib sort interpretation of this function, a LessFn in sortby should only compare a single field in your datastructure's elements. Multiple LessFns can be composed with Chain to create a composite Less implementation to pass to sort.
