  Description     : Fast directory traversal for Golang

 Fast parallel directory traversal for Golang.

 Package fastwalk provides a fast parallel version of filepath.WalkDir that is
 ~2x faster on macOS, ~4x faster on Linux, ~6x faster on Windows, allocates
 50% less memory, and requires 25% fewer memory allocations.
 Additionally, it is ~4-5x faster than godirwalk across OSes.

 Inspired by and based off of golang.org/x/tools/internal/fastwalk.

This is a dependency for fzf.
