Member Function Documentation

hasKnownOutputPaths()

bool nix::DerivationType::hasKnownOutputPaths

(

)

const

Does the derivation knows its own output paths? Only true when there's no floating-ca derivation involved in the closure, or if fixed output.

isCA()

bool nix::DerivationType::isCA

(

)

const

Do the outputs of the derivation have paths calculated from their content, or from the derivation itself?

isFixed()

bool nix::DerivationType::isFixed

(

)

const

Is the content of the outputs fixed a priori via a hash? Never true for non-CA derivations.

isPure()

bool nix::DerivationType::isPure

(

)

const

Whether the derivation is expected to produce the same result every time, and therefore it only needs to be built once. This is only false for derivations that have the attribute '__impure = true'.

isSandboxed()

bool nix::DerivationType::isSandboxed

(

)

const

Whether the derivation is fully sandboxed. If false, the sandbox is opened up, e.g. the derivation has access to the network. Note that whether or not we actually sandbox the derivation is controlled separately. Always true for non-CA derivations.
