Struct ChunkMapping 

pub struct ChunkMapping {
    pub logical: u64,
    pub length: u64,
    pub stripe_len: u64,
    pub chunk_type: u64,
    pub num_stripes: u16,
    pub sub_stripes: u16,
    pub stripes: Vec<Stripe>,
}

A chunk mapping: maps a range of logical addresses to physical device locations.

Fields

logical: u64

Starting logical byte address of this chunk.

length: u64

Length of this chunk in bytes.

stripe_len: u64

Stripe length for striped profiles (RAID0/10/5/6).

chunk_type: u64

Chunk type flags (DATA/METADATA/SYSTEM + RAID profile).

num_stripes: u16

Number of stripes (device copies/segments).

sub_stripes: u16

Sub-stripes for RAID10.

stripes: Vec<Stripe>

Physical device locations for each stripe.
