newtype StorePath a

A path in the nix store. It carries a phantom a to differentiate between Derivation files and Realized paths.

Constructors

StorePath

Fields

• fromStorePath :: FilePath

Instances

Eq (StorePath a)

Defined in Foreign.Nix.Shellout.Types

Methods

(==) :: StorePath a -> StorePath a -> Bool

(/=) :: StorePath a -> StorePath a -> Bool

Show (StorePath a)

Defined in Foreign.Nix.Shellout.Types

Methods

showsPrec :: Int -> StorePath a -> ShowS

show :: StorePath a -> String

showList :: [StorePath a] -> ShowS

data Derivation

A nix derivation is a complete build instruction that can be realized.

data Realized

Once a derivation is realized, the finished output can be used.
