Struct ReadCacheOptions 

pub struct ReadCacheOptions {
    pub capacity_bytes: usize,
    pub page_bytes: usize,
    pub max_in_flight: usize,
    pub read_ahead_pages: usize,
    pub max_prefetch_in_flight: usize,
}

Encoded-page retention and speculative I/O limits. No disk cache is created.

Share one native cache across embedded scandal instances to bound their combined retained bytes. Decoded batches and buffers held by callers are outside this budget.

Fields

capacity_bytes: usize

Maximum retained encoded bytes; zero bypasses payload caching.

page_bytes: usize

Page size; the last page is clipped to the immutable object’s length.

max_in_flight: usize

Maximum physical reads in flight, including speculative reads.

read_ahead_pages: usize

Adjacent pages eligible for opportunistic read-ahead; zero disables it.

max_prefetch_in_flight: usize

Maximum speculative reads in flight across this cache.
