Struct IoSnapshot 

pub struct IoSnapshot {
    pub descriptor_bytes: u64,
    pub manifest_bytes: u64,
    pub index_bytes: u64,
    pub seed_bytes: u64,
}

A point-in-time copy of IoCounters. Subtract two to attribute bytes to an interval.

Fields

descriptor_bytes: u64

Descriptor-blob bytes read.

manifest_bytes: u64

Field-manifest bytes read.

index_bytes: u64

Hierarchical-index-node bytes read.

seed_bytes: u64

Seed-node bytes read.

Implementations

impl IoSnapshot

pub fn delta(&self, later: &IoSnapshot) -> IoSnapshot

Bytes fetched in the interval (self, later], saturating at zero so a counter reset can never underflow into a fabricated huge number.

pub fn total(&self) -> u64

The total physical bytes across every class.

pub fn plus(&self, other: &IoSnapshot) -> IoSnapshot

Add other class-by-class.
