Overview ¶

Package slices provides a rich set of generic functions for common operations on slices of any element type.

This package is a generated adapter that mirrors the public API of the standard Go experimental package `golang.org/x/exp/slices`. It offers a convenient way to access these common utilities for searching, sorting, comparing, and manipulating slices.

For detailed information on the behavior of specific functions, please refer to the pkg.go.dev documentation for the `slices` package.

Package slices implements the functions, types, and interfaces for the module.

Package slices contains generated code by adptool.
