Package reflectutil
Package reflectutil contains reflect utilities.
In the call graph viewer below, each node
is a function belonging to this package
and its children are the functions it
calls—perhaps dynamically.
The root nodes are the entry points of the
package: functions that may be called from
outside the package.
There may be non-exported or anonymous
functions among them if they are called
dynamically from another package.
Click a node to visit that function's source code.
From there you can visit its callers by
clicking its declaring func
token.
Functions may be omitted if they were
determined to be unreachable in the
particular programs or tests that were
analyzed.
func Swapper(slice interface{}) func(i, j int)
Swapper returns a function which swaps the elements in slice.
Swapper panics if the provided interface is not a slice.
Its goal is to work safely and efficiently for all versions and
variants of Go: pre-Go1.5, Go1.5+, safe, unsafe, App Engine,
GopherJS, etc.
