IoStats

Struct IoStats 

Source
pub struct IoStats {
    pub writes: AtomicU64,
    pub write_bytes: AtomicU64,
    pub reads: AtomicU64,
}
Expand description

One file’s I/O, counted. Per FILE: a global cursor interleaves the data file and the WAL, counting every alternation as a seek and summing both files’ bytes as one – both measured wrong before this existed.
