Member Function Documentation

◆ maybeLstat()

std::optional< SourceAccessor::Stat > nix::RemoteFSAccessor::maybeLstat ( const CanonPath & path)
overridevirtual

Implements nix::SourceAccessor.

◆ readDirectory()

SourceAccessor::DirEntries nix::RemoteFSAccessor::readDirectory ( const CanonPath & path)
overridevirtual
Note
Like readFile, this method should not follow symlinks.

Implements nix::SourceAccessor.

◆ readFile()

std::string nix::RemoteFSAccessor::readFile ( const CanonPath & path)
overridevirtual

Return the contents of a file as a string.

Note
Unlike Unix, this method should not follow symlinks. Nix by default wants to manipulate symlinks explicitly, and not implictly follow them, as they are frequently untrusted user data and thus may point to arbitrary locations. Acting on the targets targets of symlinks should only occasionally be done, and only with care.

Reimplemented from nix::SourceAccessor.

◆ readLink()

std::string nix::RemoteFSAccessor::readLink ( const CanonPath & path)
overridevirtual

Implements nix::SourceAccessor.
