Enum ProximityFilter 

pub enum ProximityFilter<'a> {
    All,
    KeyRange {
        start: Option<&'a [u8]>,
        end: Option<&'a [u8]>,
    },
    Prefix(&'a [u8]),
    EligibleKeys(&'a [Vec<u8>]),
    SecondaryEligible {
        keys: &'a [Vec<u8>],
        source_directory: &'a Tree,
    },
}

Canonical structural restriction applied before leaf scoring.

Variants

All

KeyRange

Inclusive start and exclusive end. None is unbounded.

Fields

start: Option<&'a [u8]>

end: Option<&'a [u8]>

Prefix(&'a [u8])

EligibleKeys(&'a [Vec<u8>])

Keys must be strictly ascending and unique.

SecondaryEligible

Secondary-derived keys bound to the exact source snapshot.

Fields

keys: &'a [Vec<u8>]

source_directory: &'a Tree
