Enum StreamSelector 

pub enum StreamSelector {
    All,
    Streams(Vec<StreamId>),
    PartitionClass {
        count: u32,
        index: u32,
    },
}

Which streams a plan selects. Evaluated per record from the envelope’s StreamId — never from the stream catalog — so streams created after any derived state was built still route correctly.

Variants

All

Every stream.

Streams(Vec<StreamId>)

An explicit set of stream IDs (deduplicated and sorted internally).

PartitionClass

Every stream whose ID hashes into partition index of count equal hash classes — the healing unit. The hash is the first eight little-endian bytes of the StreamId modulo count, which is uniform because stream IDs are themselves hash-derived.

Fields

count: u32

Number of partition classes.

index: u32

Which class (0-based) to select.
