NvFetcher.NixFetcher

NixFetcher is used to describe how to fetch package sources.

There are two types of fetchers overall:

1. FetchGit -- nix-prefetch-git
2. FetchUrl -- nix-prefetch-url

As you can see the type signature of prefetch: a fetcher will be filled with the fetch result (hash) after the prefetch.

Types

data NixFetcher (k :: FetchStatus)

If the package is prefetched, then we can obtain the SHA256

Constructors

FetchGit

Fields

• _furl :: Text
• _rev :: Version
• _deepClone :: Bool
• _fetchSubmodules :: Bool
• _leaveDotGit :: Bool
• _sha256 :: FetchResult k

FetchUrl

Fields

• _furl :: Text
• _sha256 :: FetchResult k
