Struct object::read::read_cache::ReadCacheRange

pub struct ReadCacheRange<'a, R: ReadCacheOps> {
    r: &'a ReadCache<R>,
    offset: u64,
    size: u64,
}

An implementation of ReadRef for a range of data in a stream that implements Read + Seek.

Shares an underlying ReadCache with a lifetime of 'a.

Fields

r: &'a ReadCache<R>

offset: u64

size: u64
