Struct FileStoreOptions 

pub struct FileStoreOptions {
    pub sync: bool,
    pub max_cached_msgs: usize,
    pub max_body_records: usize,
}

Options shared by FileStore and CachedFileStore (FR-025).

Fields

sync: bool

FileStoreSync: fsync the body/seqnum files after every write.

max_cached_msgs: usize

FileStoreMaxCachedMsgs (honored by CachedFileStore only): maximum number of message bodies held in memory; 0 means unbounded (cache every message saved this session, the original pre-FR-025 behavior).

max_body_records: usize

FileStoreMaxBodyRecords (NEW-108, audit 006): bound the body log’s index to at most this many of the most-recently-appended records; 0 (the default) means unbounded, the original behavior. When set, the oldest indexed records are dropped from the index (never physically truncated from the file – like a corrupt-tail’s unindexed bytes, they simply become unreachable) once the bound is exceeded. This is an explicit, opt-in trade-off: a bounded store can no longer serve a resend request for a sequence number old enough to have aged out of the index, so only enable it when the deployment’s own reset/rollover cadence (or downstream reconciliation) makes that acceptable – unlike log rotation, this changes resend/recovery semantics, not just disk footprint.
