Return the direct store path part of PATH, stripping components after '/gnu/store/xxxx-foo'.

Return the protocol version of STORE as an integer.

Return the store path whose hash part is HASH-PART (a nix-base32 string). Return the empty string if no such path exists.

Add the given TREE to the store on SERVER. TREE must be an entry such as:

("my-tree" directory ("a" regular (data "hello")) ("b" symlink "a") ("c" directory ("d" executable (file "/bin/sh"))))

This is a generalized version of 'add-to-store'. It allows you to reproduce an arbitrary directory layout in the store without creating a derivation.

Return the list of outputs of PATH, a .drv file.

Return the list of valid "derivers" of PATH---i.e., all the .drv present in the store that have PATH among their outputs.

Allocate a new cache for store connections and return its identifier. Said identifier can be passed as an argument to

Collect garbage from the store at SERVER. If MIN-FREED is non-zero, then collect at least MIN-FREED bytes. Return the paths that were collected, and the number of bytes freed.

Make PATH a temporary root for the duration of the current session. Return #t.

Return the info (hash, references, etc.) for PATH.

Return the hash part of PATH as a base32 string, or #f if PATH is not a syntactically valid store path.
