type LoadedResolver = ResolverWith SnapshotHash

data ResolverWith customContents

How we resolve which dependencies to install given a set of packages.

Constructors

ResolverStackage !SnapName

Use an official snapshot from the Stackage project, either an LTS Haskell or Stackage Nightly.

ResolverCompiler !(CompilerVersion CVWanted)

Require a specific compiler version, but otherwise provide no build plan. Intended for use cases where end user wishes to specify all upstream dependencies manually, such as using a dependency solver.

ResolverCustom !Text !customContents

A custom resolver based on the given location (as a raw URL or filepath). If customContents is a Either Request FilePath, it represents the parsed location value (with filepaths resolved relative to the directory containing the file referring to the custom snapshot). Once it has been loaded from disk, it will be replaced with a SnapshotHash value, which is used to store cached files.
