Struct ChangedSpan 

pub struct ChangedSpan {
    pub start: Vec<u8>,
    pub end: Option<Vec<u8>>,
}

Half-open key range that was recently changed.

start is inclusive and end is exclusive. end == None means the span extends to the end of the keyspace. Changed-span hints are performance sidecars for sync and indexing jobs; they do not change tree semantics.

Fields

start: Vec<u8>

Inclusive lower key bound.

end: Option<Vec<u8>>

Exclusive upper key bound, or None for the rest of the keyspace.

Implementations

impl ChangedSpan

pub fn new(start: impl Into<Vec<u8>>, end: Option<Vec<u8>>) -> Self

Create a half-open changed span [start, end).

pub fn from_key(key: impl Into<Vec<u8>>) -> Self

Create a changed span for one exact key.

pub fn for_prefix(prefix: impl Into<Vec<u8>>) -> Self

Create a changed span for every key under prefix.
