Enum StorePredicate 

pub enum StorePredicate {
    NameMatches(String),
    SizeAtLeast(u64),
    SizeAtMost(u64),
    FileCountAtLeast(usize),
    ContainsBytes(Vec<u8>),
    ContentsMatch(String),
    HasReference(String),
    All(Vec<StorePredicate>),
    Any(Vec<StorePredicate>),
    Not(Box<StorePredicate>),
}

Composable predicate over a StoreEntry (with optional RefIndex context for reference-aware predicates).

Variants

NameMatches(String)

Entry’s basename (e.g. hello-2.12) matches this regex.

SizeAtLeast(u64)

Entry size in bytes ≥ this value.

SizeAtMost(u64)

Entry size in bytes ≤ this value.

FileCountAtLeast(usize)

Entry’s file_count ≥ this value.

ContainsBytes(Vec<u8>)

Entry’s NAR contents contain this literal byte sequence (case-sensitive, no regex).

ContentsMatch(String)

Entry’s NAR file contents match this regex (UTF-8 lossy).

HasReference(String)

Entry references at least one /nix/store/<prefix>* path where <prefix> matches this substring.

All(Vec<StorePredicate>)

Logical AND.

Any(Vec<StorePredicate>)

Logical OR.

Not(Box<StorePredicate>)

Logical NOT.
