Package typeparams contains common utilities for writing tools that interact with generic Go code, as introduced with Go 1.18.

Many of the types and functions in this package are proxies for the new APIs introduced in the standard library with Go 1.18. For example, the typeparams.Union type is an alias for go/types.Union, and the ForTypeSpec function returns the value of the go/ast.TypeSpec.TypeParams field. At Go versions older than 1.18 these helpers are implemented as stubs, allowing users of this package to write code that handles generic constructs inline,even if the Go version being used to compile does not support generics.

This package provides supplemental Go libraries for image processing.

This package provides most of the code for running a godoc server.

Juniper is a library of extensions to the Go standard library using generics, including containers, iterators, and streams.

• container/tree contains a Map and Set that keep elements in sorted order. They are implemented using a B-tree, which performs better than a binary search tree.

• container/deque contains a double-ended queue implemented with a ring buffer.

• container/xheap contains a min-heap similar to the standard library's container/heap but more ergonomic, along with a PriorityQueue that allows setting priorities by key.

• container/xlist contains a linked-list similar to the standard library's container/list, but type-safe.

• xslices contains some commonly-used slice operations, like Chunk, Reverse, Clear, and Join.

• iterator contains an iterator interface used by the containers, along with functions to manipulate them, like Map, While, and Reduce.

• stream contains a stream interface, which is an iterator that can fail. Useful for iterating over collections that require I/O. It has most of the same combinators as iterator, plus some extras like Pipe and Batch.

• parallel contains some shorthand for common uses of goroutines to process slices, iterators, and streams in parallel, like parallel.MapStream.

• xsort contains extensions to the standard library package sort. Notably, it also has the definition for xsort.Less, which is how custom orderings can be defined for sorting and also for ordered collections like from container/tree.

• You can probably guess what's in the packages xerrors, xmath, xmath/xrand, xsync, and xtime.

The config package holds the config.json file defining the Go telemetry upload configuration and contains no actual Go code, and exists only so the config.json file can be served by module proxies.

An upload configuration specifies the set of values that are permitted in telemetry uploads: GOOS, GOARCH, Go version, and per-program counters.

The avo package presents a familiar assembly-like interface that simplifies development without sacrificing performance.
