Enum LinkPutOp 

pub enum LinkPutOp {
    Plain,
    Async,
}

How an external OUT-link write should be delivered to the lset.

Mirrors the C dbCore split between a plain link put and a put-notify-aware put: dbPutLink (synchronous, no completion callback) vs dbPutLinkAsync (issued from dbNotify, where the source record’s processing is held until the downstream put completes). pvxs’s pvalink lset realises the same split as pvaPutValue (plain, wait=false) vs pvaPutValueAsync (wait=true, which sets record._options.block so the PUT request carries the block option and the source record is parked in after_put until the server acknowledges completion) — pvxs/ioc/pvalink_lset.cpp putValue / putValueAsync.

The database selects the op from the write context: a write that originates inside a put-notify / blocking-put chain (the source record carries a completion wait-set) uses Async; a plain record-processing OUT write uses Plain.

Variants

Plain

Plain put — fire-and-forget from the lset’s perspective. Maps to pvxs pvaPutValue (wait=false) / C dbPutLink.

Async

Completion-aware put — the originating record is part of a put-notify / blocking-put chain. Maps to pvxs pvaPutValueAsync (wait=true, record._options.block) / C dbPutLinkAsync.
