Renamed to davidboers/ElmEither. That is where the repository lives now. It has not been published as a package under the new name.
Versions published as kingwither/elmeither still install under that name. 1 version of 1 come from the new location (see their notes).
Rerouted (renamed, verified). The GitHub user or repository was renamed. The tag is still there, at the new name. The Lamdera package server serves a copy recovered from https://github.com/davidboers/ElmEither.
What we checked: The repo moved to github.com/davidboers/ElmEither and tag 1.0.0 is there; its commit 3daeeb6718bb is from 2021-05-07 18:31 UTC, before the version was published (2021-05-07 18:33 UTC); elm.json is byte-identical to package.elm-lang.org's; the exposed modules match docs.json; the zip's SHA-1 is not the published one (GitHub's zip no longer comes out byte for byte the same), so the contents were checked instead.
The Lamdera compiler uses this copy and prints a one-line notice saying so. elm itself fails to download this version.

This module implements 'Either' like in Haskell.
Decodes the left side of an Either statement. Will return Nothing if the variable is on the right.
Similar to right.
Decodes the right side of an Either statement. Will return Nothing if the variable is on the left.
Similar to left.
Like left, but insured. If the variable is on the right side, a given value will be returned instead.
Like right, but insured. If the variable is on the left side, a given value will be returned instead.
This is like an enum declaration for which side is active in an Either variable.
They can not be Left and Right, because those constructors are already taken by
the above Either declaration.
Checks if two Either variables are active on the same side.
Checks if ALL the Either variables are on the same side.
