Member Function Documentation

isTrustedClient()

std::optional< TrustedFlag > nix::DummyStoreImpl::isTrustedClient ( )

inlineoverride

The dummy store is incapable of not trusting! :)

isValidPathUncached()

bool nix::DummyStoreImpl::isValidPathUncached ( const StorePath & path )

inlineoverride

Do this to avoid queryPathInfoUncached computing PathInfo that we don't need just to return a bool.

readInvalidDerivation()

Derivation nix::DummyStoreImpl::readInvalidDerivation ( const StorePath & drvPath )

inlineoverride

No such thing as an "invalid derivation" with the dummy store

Member Data Documentation

wholeStoreView

ref<WholeStoreViewAccessor> nix::DummyStoreImpl::wholeStoreView = make_ref<WholeStoreViewAccessor>()

This view conceptually just borrows the file systems objects of each store object from contents, and combines them together into one store-wide source accessor.

This is needed just in order to implement Store::getFSAccessor.
